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

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
