Answer:

The answer is

$y = 3x + 5$

Step-by-step explanation:

❃Incase you forgot what the linear equation formula is ↶

$y = mx + b$

❃Since we already have the slope, we don't need to solve for that.

➊ First: We are going to find the y-intercept.

$y = mx + b \\ 2 = 3( - 1) + b \\ 2 = - 3 + b \\ \frac{ + 3 = + 3 \: \: \: \: \: }{5 = b}$

➋Second: Plug in.

$y = 3x + 5$
