Question

A line passes through the points (4,6) and (3, 3). What is its equation in slope-intercept

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

Answer 1

y = 3x - 6

Explanation:

Find the slope of the line:

3 - 6 / 3 - 4 -> -3/-1 so the slope is 3

Now use the point-slope form to find the slope-intercept form:

y - 3 = 3 (x - 3)

y - 3 = 3x - 9 add three to each side...

y = 3x - 6
