Write an equation into Standard form that passes through the point (-1, 2) and is parallel to the line described by y = -2x + 4.

Answer 1

to be parallel, the line must have the same slope = m = -2 = the coefficient of the x term, when the equation has been solved for y

y=-2x + b where b = the y intercept. to solve for b plug in the point (-1,2)

2 =-2(-1) + b

b = 2-2 =0

y=-2x + 0

y=-2x is the parallel line through the point (-1,2)
