You only gave one pair of points so I assume you want a line going through those two points.

y = (2/3)x - 7/3

If you plot this, it is approximately a straight line (with a y error or +/-.2). An ideal straight line would have y points of 7,8,9,10,11,12 for the given x's. The formula for this line is y=.5x + 6 . The gradient (slope) is .5 and the intercept is 6.

The gradient can be calculated using the formula:

(y2-y1)/(x2-x1) = (12-7)/(10-2) = 5/10 = 0.5

The intercept is where the graph crosses the y axis and can be calculated once the gradient is known by substituting any associated x and y into the formula: y=.5x + i (where i is intercept). For example the point (2,7) gives 7 = .5(2) +i

7 = 1 + i

6 = i

or using (12,12), 12 = (.5)(12) + i

12 = 6 + i

6 = i

The gradient can be calculated using the formula:

(y2-y1)/(x2-x1) = (12-7)/(10-2) = 5/10 = 0.5

The intercept is where the graph crosses the y axis and can be calculated once the gradient is known by substituting any associated x and y into the formula: y=.5x + i (where i is intercept). For example the point (2,7) gives 7 = .5(2) +i

7 = 1 + i

6 = i

or using (12,12), 12 = (.5)(12) + i

12 = 6 + i

6 = i

You could use Concatenate command. Means to join together.

B2 = Concatenate A2, ,H2 Note the space in middle, for dentist chico. Otherwise will be dentistchico

The site seems to eat the plus signs I enter, so I will use PLUS to symbolize addition.

To find the equation of the straight line (y = a*x PLUS b) that passes through two points P1(x1,y1) and P(x2,y2) , you need to use

1. the coordinates of the points to calculate the slope a (gradient) as a=(y2-y1)/(x2-x1)

2. Replace the calculated value of a in the equation and write that one of the points ( P1(x1,y1) for example) satisfies the equation. In other words y1=a*x1 PLUS b.

Here y1 and x1 are known values, a has been calculated, and only b is still unknown. You can now use the equation y1=a*x1 PLUS b to calculate b as

b=(y1-a*x1)

Example: Equation of the line through (1,5) and (3,6)

Calculate the slope (gradient) of the line as a=(y2-y1)/(x2-x1) where y2=6, y1=5, x2=3, and x1=1. You should get a=(6-5)/(3-1)=1/2

The equation is y=(1/2)x PLUS b, where b is not known yet.

To find b, substitute the coordinates of one of the points in the equation. Let us do it for (3,6).

The point (3,6) lies on the line, so 6=(1/2)*3 PLUS b.

Solve for b: 6 MINUS 3/2=b, or b=9/2=4.5

Equation is thus y=(x/2) PLUS 9/2 =(x PLUS 9)/2

I trust you can substitute you own values for (x1,y1, x2,y2) to duplicate the calculations above.

Calculate the slope (gradient) of the line as a=(y2-y1)/(x2-x1) where y2=1, y1=0, x2=0, and x1=-6. You should get a=(1-0)/(0-(-6))=1/6

The y-intercept is the y-cordinate for x=0. Its value is 1.

The equation is then y=(x/6) 1.

The y-intercept is the y-cordinate for x=0. Its value is 1.

The equation is then y=(x/6) 1.

Apply a different shape
fill
You can fill a selected shape (such as data markers, titles, data labels, or
a legend) with a solid color, gradient, picture, or texture. You cannot use
shape fill to format lines in a chart (such as gridlines, axes, trendlines, or
error bars).

On a chart, click the chart element that you want to change, or do the following to select it from a list of chart elements:

**Format** tab, in the **Shape Styles** group,
click **Shape Fill**

get a sheet of graph paper. draw a line vertical and draw another line in the center perpendicular to the vertical. the meeting point is 0,0 - the upper right quadrant is X-Y. the bottom right quadrant is Y -X, the left bottom is -Y -X and what's left is -X +Y.

take your first coordinate. count up 2 and to the right 3. make a point. second coordinate - count up 4 and over right 1, make a point. now join the two points with a straight line. measure the distance between the points.

Relative cell reference is address of cell , when copied from one cell to another gets changed automatically.

e.g. Put formula in cell c5 as A5+1 when you copy this from c5 to c6 the address of A5 will automatically changed to A6.

Absolute Cell Reference

As above now put formula in cell C5 as $A$5+1 ,now copy this formula from C5 to C6 if you this formula youwill find cell Address of A5 does not changed.

Mixed Cell Reference:

If we put Dollar ($) sign before Alphabetic cell address i.e.$c5 then even if you copy this formula in any cell , coloumn (c) will remains constant.

Similarly if we put Dollar ($) sign before Numeric cell address i.e.c$5 then you copy this formula in any cell row address of the cell remains same.(5).
