Question

Use point-slope form to write the equation of a line that passes through the point

(12, 10) with slope 1/3.

Answer 1

y - 1/3x - 10 + 4 = 0

Explanation:

What we know:

x = 12

y = 10

slope (m) = 1/3

y - y1 = m(x - x1) Point-slope form

Substitute in the values we have

y - 10 = 1/3(x - 12)

Bring all the values to one side

y - 10 - 1/3(x - 12) = 0

y - 1/3x - 10 + 4 = 0
