Question

Find the equation of the line parallel to line h that
passes through (-4, 2).

Answer 1

your question seems incomplete (you probably have two points for the line h)

Explanation:

the slope of a line is y=mx+b

given the two points we can compute the slope

let's find the slope first (which is m)

slope=rise/run which is also m=(y2-y1)/(x2-x1)

then you substitute to find b using y=mx+b (we determined m using the slope equation).
