Answer:
-456 I think but I could be wrong though
(-3,-5)(2,4)
slope(m) = (4 - (-5) / (2 - (-3) = (4 + 5) / (2 + 3) = 9/5
y - y1 = m(x - x1)
slope(m) = 9/5
(2,4)...x1 = 2 and y1 = 4
sub
y - 4 = 9/5(x - 1)....this is the correct answer
the student figured the slope wrong....it is 9/5...not -9/5
Y=2x+5
goes up by 2, which is the gradient and 5 is the y intercept
The constant is 15, divide 45 by 3 then you’ll get 15. multiply 15 with the minutes and you’ll get the sit-ups
