What is the first step to writing an equation in slope-intercept form using the given points: (-3, 1), (-4, -2)? what is the rate of change
a) find the slope using the slope formula y = mx + b; m = -3
b) find the slope using the slope formula
y2 - y1
x2 - x1
; m = 3
c) find the slope using the slope formula
y2 - y1
x2 - x1
; m = -3
d) find the slope using the slope formula y = mx + b; m = 3

Option B.

The first  step is find the slope using the formula  

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

where

m is the slope

is the y-intercept

so

The firs step is determine the slope of the linear equation

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

we have

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

substitute the given values in the formula

Remember that

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

so

The rate of change is 3
