The equation is y=-3x+7! hope it helps!
For the bubble numbers put the second box in there, and for the chart put the first box.
What you would have to do is distribute your three to each number in the parentheses using multiplication so your answer would be 6y+15
The improper fraction form is 70/8.
I hope this helps you, please Brainliest me, and have a great day! :D
