Question

What is the equation of a line that passes through the point (-2,4) and is parallel to the line y=3?

A) x=-2 B) y=4 C) x=4 D) y=-2

Answer 1

y = 3 is a horizontal line with a 0 slope. A parallel line will have the same slope.
now use y = mx + b
slope(m) = 0
(-2,4) x = -2 and y = 4
now sub
4 = 0(-2) + b
4 = 0 + b
4 = b
therefore your equation is : y = 0x + 4, or just y = 4

Answer 2

So, B?

Answer 3

yes.. B
