Slope is usually designed by the letter m. m=delta y/delta x or change in y/change in x or (y2-y1)/(x2-x1).

What we know.

m = -17 (very very steep, with a negative slope, going up to the left)

Point (5, -3)

Point (u,-1)

Putting everything into the above equation, we get

m = (-3-(-1))/(5 - u) , where m =-17

-17 = (-3 + 1)/(5 - u)

-17 = (-2)/(5-u)

To get rid of the fraction, multiply both sides by (5 - u)

-17(5-u) = -2

-85 + 17u = -2

Add 85 to both sides to get rid of the -85.

-85 + 85 +17u = -2 + 85

17u = 83

Divide both side to get u by itself.

17u/(17) = 83 / 17

u = 4.89 (rounded to 2 decimals)

Good luck,

Paul

The "slope intercept form of the equation of a (the) line" is y=mx+b, where m is the slope of the line and b is the y-intercept.

We are given the slope of 1/2, so m= 1/2.

We can now write y=1/2 x + b.

Since the point (-2,-3) is on the line, we can substitute it in and solve for b. We put the -2 in for x and -3 in for y.

-3 = 1/2(-2) +b

-3 = -1 + b

-3 + 1 = -1 + b +1

-2 =b

Thus, the equation of the line is y= 1/2 x -2

To check if we did this correctly, plug in the point (-2, -3) to see if it works.

-3 = 1/2 (-2) -2

= -1-2

= -3

We are given the slope of 1/2, so m= 1/2.

We can now write y=1/2 x + b.

Since the point (-2,-3) is on the line, we can substitute it in and solve for b. We put the -2 in for x and -3 in for y.

-3 = 1/2(-2) +b

-3 = -1 + b

-3 + 1 = -1 + b +1

-2 =b

Thus, the equation of the line is y= 1/2 x -2

To check if we did this correctly, plug in the point (-2, -3) to see if it works.

-3 = 1/2 (-2) -2

= -1-2

= -3

To graph (-3, -3) we start at the origin (0,0) and go 3 squares to the left and then 3 squares down.

Slope is defined in many ways, including rise/run, delta y/ delta x, etc.

Since 0 divided by anything is 0, the rise must be zero, so the slope of 0 is a horizontal line.

Put the point and the slope together, we have a horizontal line going through (-3,-3).

Good luck.

You have to provide the graph. Depending on the graph, the slope of the secant line can be just about anything.

Points don't have slopes.

The slope of the line going through those two points is 2/3.

The slope of the line going through those two points is 2/3.

- Transform this equation to its functional form:
- 9y=-3x+17 or
**y=(-1/3)x+17/9** - In the last equation, the slope is the coefficient of x, namely
**-1/3.** - A line parallel to this one must have the same slope (-1/3).
- So the equation of your line starts this way:
**y=(-1/3)x+b.** - To identify (calculate)
**b**, you must make use of the fact that the parallel line passes through the point (1,5). - That means that the coordinates of the point (1,5) satisfy the equation of the parallel line y=(-1/3)x+b
- Substitute 5 for y, and 1 for x and solve for b.

slope of side lm by applying slope =(y2-y1)/(x2-x1)

slope of lm=0

slope of mn=5/-3 = -5/3

slope of ln= 5/3

so sum of slopes =0

slope of lm=0

slope of mn=5/-3 = -5/3

slope of ln= 5/3

so sum of slopes =0

Sorry we dont do homework its cheating

difference in y (Y2-Y1) divided by difference in x (X2-X1). Example: 1st point (5,3) and second point (10,6) means subtract 3 from 6 (2nd y value from first)= 3- this is your numerator. now subtract second X value from firt X value (10-5)= 5; this is the denominator. the slope (m) is 3/5 or .6
