Question

The equation of line c is y=8/7x-9. Line d includes the point (6,6) and is parallel to line c. What is the equation, in slope-intercept form, of line d?

Answer 1

d: y=8/7*x-6/7

Explanation:

Line c parallel to line d, then m=8/7

d includes the point (6,6)

d: y-y1 =m(x-x1)

(6,6)=(x1,y1)

d: y-6=8/7(x-6)

y-6=8/7*x-8/7*6

y-6=8/7*x-48/7

y=8/7*x- 48/7+6

y=8/7*x-48/7+42/7

y=8/7*x-6/7
