Question

The equation of the line with slope 2 that goes through the point (-9, 15) can be written in the form y=mx + b, where Preview m= Preview

Answer 1

Answer:

$y = 2x + 33$

Step-by-step explanation:

The equation of the line has the following format:

$y = mx + b$

In which m is the slope of the line.

We want the equation of a line:

That has slope 2, so $m = 2$

$y = 2x + b$

Also that goes through the point (-9, 15). This means that $x = -9, y = 15$. So

$15 = 2(-9) + b$

$15 = -18 + b$

$b = 33$

The equation of the line is:

$y = 2x + 33$
