Answer:

Intersect: (4 4/7 , 2 6/7)

Step-by-step explanation:

A: slope (m)= (-10-8) / (-9 - 10) = 18/19

Equation: y-8 = 18/19 * (x-10)

18x -19y = 28 (1)

B: slope (m) = (12 - -2) / (0 - 7) = -2

equation: y-12 = -2 *(x - 0)

2x + y = 12

38x + 19y = 228 (2)

(2) + (1): 56x = 256 x = 4 4/7

y = 12 - 2x = 12 - 64/7 = 2 6/7
