Find the slope of the line that passed through (5,8) and (1,13)

Slope is -5/4

Step-by-step explanation:

to find the slope of two points,  you subtract the y values/x values. So 8-13/5-1 which ends up as -5/4 which is the answer.

b=-3

Step-by-step explanation:

-11b+7=40

-7         -7

-11b=40-7

-11b=33

-11b/-11=33/-11

b=-3

CHECK:

-11b+7 = 40

Substitute -3 for b:

-11(-3)+7=40

Solve:

33+7=40

40=40

Therefore b does in fact equal -3.
