Question

Write the equation in y=mx+b form please????

Answer 1

`y = - 2x - 5`

Step-by-step explanation

We can use any two points to determine the slope.

The line passes through;

(-3,1) and (-5,5).

The slope is given by

`m = (y_2-y_1)/(x_2-x_1)`

This implies that;

`m = (5 - 1)/( - 5 - - 3)`

`m = (4)/( - 2) = - 2`

We can now find the equation using the formula;

`y-y_1=m(x-x_1)`

`y - 1 = - 2(x + 3)`

Expand:

`y = - 2x -6 + 1`

`y = - 2x - 5`
