Question

Line s has an equation of y=-1/7x-10. Parallel to line s is line t, which passes through the point (9,-2). What is the equation of line t?

Answer 1

y = -1/7x + 5/7

Explanation:

The slope of a parallel line is the same as the original.

Find the new y-intercept.

y = -1/7x + b

-2 = -1/7(9) + b

-2 = -9/7 + b

5/7 = b

y = -1/7x + 5/7

Best of Luck!
