Question

Complete the equation of the line through (6,-6) and (8,8).
Use exact numbers.
y=?

Answer 1

7x-48

Explanation:

Answer 2

y = 7x - 48

use slope formula so, y2 - y1 over x2 - x1 to get your m value or your slope which is 7. then plug in the slope and a random set of point so I used (6, -6). -6 = 6(7) + b, simplify.
-6 = 42 + b, subtract 42 which leaves you with b= -48. hope this helps :)
