Answer:
x-intercept = 10
y-intercept = -8
Step-by-step explanation:
![4x-5y=40](https://tex.z-dn.net/?f=4x-5y%3D40)
To identify the y-intercept, we will need to format the equation in the form
. We can start by subtracting
from both sides of the equation:
![-5y=-4x+40](https://tex.z-dn.net/?f=-5y%3D-4x%2B40)
Divide both sides of the equation by the coefficient of
, which is
:
![y=\frac{-4}{-5} x - 8](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B-4%7D%7B-5%7D%20x%20-%208)
The
is representative of the y-intercept in
.
Identify
in the equation
:
![b=-8](https://tex.z-dn.net/?f=b%3D-8)
Therefore, our y-intercept is -8.
To solve for the x-intercept, replace the
in the equation
with a zero:
![0=\frac{-4}{-5} x - 8](https://tex.z-dn.net/?f=0%3D%5Cfrac%7B-4%7D%7B-5%7D%20x%20-%208)
Add
to both sides of the equation:
![8=\frac{-4}{-5} x](https://tex.z-dn.net/?f=8%3D%5Cfrac%7B-4%7D%7B-5%7D%20x)
You can go ahead and divide
by
to get rid of the fraction:
![8=0.8x](https://tex.z-dn.net/?f=8%3D0.8x)
Divide both sides of the equation by the coefficient of
, which is
:
![10=x](https://tex.z-dn.net/?f=10%3Dx)
Therefore, our x-intercept is 10.
