Write an equation for the line, given that m=0 and the y-intercept is (0,2). a y=-2x b y=-2x-2 c y=-2 d y=0

As this line has a slope of zero, so it is a horizontal line (parallel to the x-axis).

As it intersects y-axis at (0,2), then its equation is just y=2

Check again your choices

Y = mx + c
using the point 0,2
2 = 0 ( 0 ) + c
Hence c = 2
and y = 2

Ithink if im not mistaking b is -3 but im not a 100% sude
