Question

What is the equation of a line, in the general form, with a slope of-2an a y-intercept of 8? 1) x+2y-8=0, 2) 2x+y-8=0, 3) 2x-y+8=0

Answer 1

y=mx+b

m=sloe

b=yint

given

slope=-2

yintercept=8

Explanation:

y=-2x+8

add 2x to both sides

2x+y=8

minus 8 both sides

2x+y-8=0

Answer 2

It is 3 but it is different a little bit because you need to move the y to the other side
