Option B.

The first step is find the slope using the formula $m=\frac{y2-y1}{x2-x1}$

The rate of change is m=3

Step-by-step explanation:

we know that

The equation of a line in slope intercept form is equal to

y=mx+b

where

m is the slope

is the y-intercept

The firs step is determine the slope of the linear equation

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

(-3,1) and (-4,-2)

substitute the given values in the formula

$m=\frac{-2-1}{-4+3}$

$m=\frac{-3}{-1}$

m=3

Remember that

In a linear equation the rate of change is a constant and is equal to the slope of the line

The rate of change is 3

P'(head)=65/100

$\frac{65}{100}$

Step-by-step explanation:

Total flip=100 times

Land on heads=65 times

65 over 100.
