### 8x+5y=-25 help me find the x Andy intercepts

To find the x-intercept, set y equal to zero and solve for x.
To find the y-intercept, set x equal to zero and solve for y.

In this case the x-intercept is -3 1/8 and the y-intercept is -5.

### In the following data set Y is a dependent variable.y=7.1,8.2,8.8,10.0,11.0,11.8;X=2.0,4.0,6.0,8.0,10.0,12.0 find gradient,intercept,mathematical relationship

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

### X and y intercepts

First of all you equation is not one : it has nothing on the right side of the = sign. But to answer the general question let us write the equation as 50+25x-5y=0
X-intercept (also know as roots) There may be several
Definition: X-intercepts are those values of the independent variable x for which y=0. For a straight line there con be at most 1 x-intercept.
To find the intercept, set y=0 in the equation of the line and solve for x
50+25x-5(0)=0 or 50+25x=0. The solution is x=-(50/25)=-2

Y-intercept (also know as the initial value. There can only be 1 y-intercept, otherwise the expression does not represent a function.
Definition: It is the value of the dependent variable y when x=0 (where the function crosses the y-axis
To find it, set the x-value to 0 in the equation of the line.
50+25x-5y=0
50+25(0)-5y=0, or 50-5y=0. The solution is y=50/5=10
The straight line cuts the x-axis at the point (-2, 0) and the y-axis at the point (0,10)

### Finding x and y intercepts

I will not try to make sense of the context (there is no a). You have a linear relation between two variables x and s (y). Here is how you find the x- and y-intercepts.
x-intercepts (or zeros, roots).
The x-intercepts are the values of x when y=0. There could be several x-intercepts.
Set y=0 in the relation 90=6x+3(0) or x=90/6=15. Note: for a linear function y=ax+b there is only one x-intercept.x=-b/a

y-intercept. For a function there can only be one y-intercept.
It is the value of y when x=0
Set x=0 in 90=6(0)+3y, This gives y=90/3=30
The coordinates of the points of intersection of the line with the axes are (15, 0) and (0,30).

### 10x+y=9

Isolate the y by subtracting 10x from both sides to get y=9-10x .

The slope is the factor of x, in this case -10 .
The intercept is the constant term, in this case 9 .

### -6x-3y=27

The x intercept is where your line will cross the x axis. Therefore, the value for y at this point is 0. Substitute 0 for y in this equation and solve for x.

6x + 3(0) = 27
x = 27/6
x = 4 1/2

x intercept = (4 1/2, 0)

Follow the same reasoning for the y intercept.

6(0) + 3y = 27
y = 27/3
y = 9

y intercept = (0,9)

Now plot these two points and draw your line through them.

### Find the x- and y-intercepts and graph the equation plotting the intercepts. Please show all of your work. Submit your graph to the Dropbox.5x-4y=-10

Use the definitions of the intercepts.
x-intercepts (or zeros or roots) are the values of the independent variables that make the function equal to zero. To obtain an intercept set y=0 in equation : 5x=-10, mean x=-10/5=-2
y-intercept: value of y when x=0.
Just set x=0 in equaltion and solve for y
-4y=-10, gives y=5/2

And Sorry, I cannot enter the answer in the drop box.

### How do I use this calculator to find the x and y intercepts when the problem has both the x and y letters. it will not allow me to enter the full equation. example problem is 2x-5y=20 and I need to find...

x-intercept (or zero of the function)
Set y=0 in the equation and solve fo x: 2x-5(0)=20 and x=20/2=10

y-intercept (initial value)
Set x= 0 in the equation and solve for y: 2(0)-5y=20 and y=20/(-5)=-4

If the equation is in the slope-intercept form y=ax+b
1. y-intercept is b
2. To get the x-intercept ( zero of the function) Set y=0=ax+b, and x=-b/a
