# Chapter 1, Equations and Graphs - Section 1.3 - Lines - 1.3 Exercises - Page 112: 3

$y-2 = 3(x-1)$

#### Work Step by Step

RECALL: The point-slope form of a line's equation is $y-y_1 = m(x-x_1$ where $(x_1, y_1)$ is a point on the line. Thus, the point-slope form of the equation of a line with a slope of $3$ and passes through the point $(1, 2)$ is: $y-2 = 3(x-1)$
