The expression of the problem is, 8x.
where "x" stands for the number of dogs. so you would then substitute x with 12. Then you would solve the problem to get your answer.(8•12)
Y=5x-3. First, you have to find the slope, which is 10/2 or 5/1. Then, you plug in the x and y with either of the 2 coordinates (I chose the first), and sole for the y-intercept.
