Answer:
y=5x+44
Step-by-step explanation:
Parallel lines have equal gradients therefore the line will have a gradient =5
Substitute the gradient into the equation y= mx+c. You'll get something like this: y=5x+c
Substitute the given point into the equation. You'll get something like this: 9=5(-7)+c
Calculate the value of c. You'll get 44 as the value of c.
Then substitute the value of c into the original equation. You'll get y= 5x+44
