The slope in short is:
4/7
Well just looking at the points itself, the point (0,2) is the y intercept.. and the only answer choice you have with 2 as the y intercept is C.
We can use the FOIL method to solve.
(5x + 3)(7x - 7)
(5x * 7x) + (5x * -7) + (3 * 7x) + (3 * -7)
35x - 35x + 21x - 21
0 + 0
0
Best of Luck!
