Question

What are the intercepts of the line 5x+y=20

A. x - intercept 4 ; y - intercept 20

B. x - intercept 20 ; y - intercept -4

C. x - intercept -4 ; y - intercept -20

D. x - intercept -20 ; y - intercept -4

Answer 1

first put it in a slope intercept form
y=mx+b
do this by subtracting 5x from both sides

then let x = 0

y=?

this is the y intercept

Answer 2

can you go into more detail when you say both sides? @zpupster

Answer 3

here
5x-5x+y=20-5x rearranging
y=5x+20

Answer 4

sorry
imean
y= -5x+20

Answer 5
