Find an equation of the line that goes through the points (-9,-20) and (-8,-17). write your answer in the form y = m x + b .

y = 3x + 7

Step-by-step explanation:

First, we will solve for the slope (m).

The formula for slope is: m =

m = --- enter the points into the formula

m = --- simplify

m = 3 --- simplify

Now we will solve for the y-intercept (b).

y = mx + b

y = 3x + b --- substitute the slope into the equation

-20 = 3(-9) + b --- substitute the x and y of either point into the equation

-20 = -27 + b --- simplify

7 = b --- add 27 to both sides

b = 7

Done.

y = 3x + 7

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
