It’s 28 : 12 because we have the equation
7 : 3 which if you multiply both of
those by 4 you’ll get 28 : 12

If the graphs of the linear equations in a system are parallel, what does that mean about the possible solution(s) of the system? a. there are infinitely many solutions. b. there is no solution. c. there is exactly one solution. d. the lines in a system cannot be parallel.

Complete the equation of the line through (−10,3) and (−8,−8). use exact numbers.
