: Find the y-intercept and the x-intercept for the equation
-8x + y = 28
-8(0) + y= 28
Y=28
Y intercept is (0,28)
-8x + 0 =28
-8x = 28
X intercept is (-2/7,0) or (-4/14,0)????
Can you help me which answer is right and why?
Thank you!

x-intercept


To find the x-intercept, plug in and solve for x


Start with the given equation.


Plug in .


Simplify.


Divide both sides by to isolate .


Reduce.


So the x-intercept is .


------------------------------------------


y-intercept


To find the y-intercept, plug in and solve for y


Start with the given equation.


Plug in .


Multiply and 0 to get 0.


Simplify.


So the y-intercept is .
