Aline passes through the points r(-2,5) and s(-1,2) write the equation of the line through the point a(5,0) that is parallel to rs

The square PQRS has vertices P(-8,4), Q(-5,4), R(-5,1), and S(-8,1). A student determined that the equation of the line QS is y=-1x+9. Evaluate the students response.

B.

The student calculated the y-intercept correctly but did not calculate the slope correctly.

No he does not because he can only cover 12 square feet from 15 square feet which he will still need 3 more. this is because if 3×5=15 square feet and 15-12=3 which thats the answer
