Answer:
m= 19
Step-by-step explanation:
In a linear function the rate of change of y-variable respect x-variable must be constant. In mathematical terms:
Δy/Δx = constant
Given two points of the function: (x1, y1) and (x2, y2), Δy = (y2 -y1) and Δx = (x2 -x1). So,
Δy/Δx = (11 -27)/(12-10) = -8
(m -27)/(11-10) = -8
(m -27) = -8*(11-10)
m = -8 + 27
m = 19
