Question

Find an equation for the line with the given properties. Express the equation in slope-intercept form.

Slope = 2; containing the point (-8,2)

What is the equation of the line?

y=

(Type your answer in slope-intercept form.)

Answer 1

y = 2x + 18

Explanation:

This is slope intercept form: y = mx + b

m = slope

b = y-intercept

We are already given the slope, 2

y = 2x + b

Now we just need to find b, so plug in the given coordinates

2 = 2(-8) + b

2 = -16 + b

Add 16 to both sides

2 = -16 + b

+ 16 + 16

b = 18

Now place in the new b into the the equation

y = 2x + 18
