The equation for line u can be written as y= – 2x+10. Line v, which is parallel to line u, includes the point ( – 1,2). What is the equation of line v?

Question

Write the equation in slope-intercept form. Write the numbers in the equation as simplified proper fractions, improper fractions, or integers.

Answer 1

y = mx + b

Parallel lines have the same slope(m).

2 = (-2)(-1) + b

2 = 2 + b

b = 0

Well, that would be y = -2x + 0, but mathematicians are lazy, so...

y = -2x
