Question

What is the equation of the line that passes through (6,2) and (8,0)

Answer 1

y = -x + 8

Explanation:

First find the slope (m):

m = (0-2) / (8-6) = -1

Next put one of the points (I pick (8,0)) into the point-slope formula:

y-y1 = m(x-x1)

y-0 = -1(x-8)

Now write it in slope-intercept form:

y = -x + 8
