Answer 1

To find which of the graphs matches the line, you first need to solve the equation for y. Step-by-step:
(y+1)=(3/5)(x-3)
(y+1)=(3/5)x-(9/5)
y=(3/5)x-(14/5)
Thus, first, you want to look at where the y-intercept is. (-14/5) is equal to -2.8. The only graph that matches that is C. However, to be on the safe-side, also check the slope (rise over run). In this case, it is (3/5) and, looking at the graph of C, you can see that the slope matches that. If you begin at the y-intercept, go up three units, then to the right five units, you will intercept the line again.

Thank you both :)
