Question

Someone please help! ATTACHMENT (just the circled one)

Answer 1

4 (3x+9)-3(5y+7) =11

distribute

12x +36 -15y -21 =11

12x -15y +15 =11

subtract 15 from each side

12x -15y =-4

subtract 12x from each side

-15y= - 12x-4

divide by -15

y = -12/-15 x -4/-15

y = 4/5 x  + 4/15

slope = 4/5

y intercept = 4/15
