Answer: 6= -7/4
Step-by-step explanation: I only have time to do 6 but here’s the explanation:
So you first look at the formula for slope: m= y2-y1/x2-x1. Then you set up the formula with your given slope: -8-6/0-(-8). Then you simply calculate. -8-6 equals -14 and 0-(-8) equals 8. Then you simplify (divide by 2) to get the answer of -7/4.
