Answer : 2
Step-by-step explanation:
Slope is a ratio, Slope = rise/run. This can also be described as "the change in Y" / "The change in X"
So, using the table, find the rate of change in the y-values and the x-values.
y = mx + b
slope : m
x=-7, y=2 : -7m + b = 2 (1)
x=-6, y=4 : -6m + b = 4 (2)
(2)-(1) => m= 2
