Question

(0,1) (3,-8) linear equation

Answer 1

The answer is

`y = - 3x + 1`

Explanation:

❃Incase you forgot what the linear equation formula is ☟

`y = mx + b`

❃Incase you also forgot, The is what the slope formula is ☟

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

➊ First: We are going to be solving for the slope.

`m = ( - 8 - 1)/(3 - 0) = ( - 9)/( \: \: \: 3) = - 3`

➋Second: We find the y-intercept.

`y = mx + b \\ - 8 = - 3(3) + b \\ - 8 = - 9 + b \\ ( + 9 = + 9 \: \: \: \: \: )/(1 = b)`

➌Third: Plug in.

`y = - 3x + 1`
