y-intercept is -3.
Slope can be counted. Slope from left to right is vertical change +3, horizontal change 4.5, for slope 3/4.5 or 6/9 or simplified, 2/3.

, the slope-intercept form.

linear equation is: where is a slope and is a y-intercept; so, we need and
from the graph we see that
if =>
and
if => => a y-intercept
then we will use these points to set the system of two equations to find and
........if ,, and
.........solve for

....simplify, divide both numerator and denominator by

so, your equation is:
