Answer:
Slope = (Y2 - Y1) / (X2 -X1)
Slope = (8 -10) / (5 -2)
Slope = -2 / 3
7/3 × 5/12 = 35/36
....................................
The answer would be 20 degrees
Step-by-step explanation:
E3, E6, E11, E7: no solution
E1, E12 : 1 solution
E2, E8, E10 : infinite solutions
6x+8y=-32
8y=-32-6x
8y/8 -6x/8
y=-3/4x-4
