Question

There is a line that includes the point (2, 4) and has a slope of 3. What is its equation in

slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answer 1

Answer: y = 3x - 2

Explanation:

slope intercept: y = mx + b, where m is the slope and b is the y-intercept.

Thus, because you already know the slope, you can simplify the equation to

y = 3x + b.

Then plug in the provided point to get, 4 = 3(2) + b

4 = 6 + b

-2 = b

Thus,

y = 3x - 2
