Question

This one I am stuck... Find the x-intercept of the equation of the line: -2y + 16x = -4.

Answer 1

My mind is saying 4

Answer 2

oops.. -4

Answer 3

for x int put y=0

Answer 4

okay well we have to put this in y=mx+b form

-2y + 16x = -4.

-2y=-16x-4

y=8x+2

now we set y=0 and solve for x

0=8x+2
-2=8x

x=-.25

-.25 is the x-intercept

Answer 5

no brent

Answer 6
