Question

The equation of line AB is y = 2x + 4. Write an equation of a line parallel to line AB in slope-intercept form that contains point (3, −2).

my friend says

y = -1/2x − 1/2

but i think its y=2x+4?

Answer 1

Slope will be -(1/2)

use y = -(1/2) x + b to find b and solve the problem.

Answer 2

you are trying to find a parallel line, which means it has the same slope

Answer 3

therefore it is y=2x+b. then you use (3, -2) to solve for b

Answer 4

hope i helped
