Question

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

Answer 1

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

Answer 2

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
