Answer:
Slope is equal to the change in y over the change in x , or rise over run.
m=change in y/ change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m=y2−y1/x2−x1
Substitute in the values of x and y into the equation to find the slope.
m=0−(2)/9−(5)
Simplify.
m=−12

Answer:
The distance between A and B is 13.6
Step-by-step explanation:
Distance formula=√(x2-x1)²+(y2-y1)²
Where
x1=-7
x2=6
y1=-1
y2=-5
Putting in the formula
Distance=√(6+7)²+(-5+1)²
D=√(13)²+(-4)²
D=√169+16
D=√185
D=13.6
