Question
graph this line:
$y - 3 = \frac{1}{5}(x + 8)$
click to select points on the graph.
Step1: Identify point from point-slope form
The equation $y - 3 = \frac{1}{5}(x + 8)$ is in point-slope form $y-y_1=m(x-x_1)$, so one point is $(-8, 3)$.
Step2: Find second point using slope
Slope $m=\frac{1}{5}$, so from $(-8,3)$, move 5 right, 1 up: $x=-8+5=-3$, $y=3+1=4$. The second point is $(-3, 4)$.
Step3: Find y-intercept (optional check)
Rewrite to slope-intercept form:
$y = \frac{1}{5}x + \frac{8}{5} + 3$
$y = \frac{1}{5}x + \frac{8}{5} + \frac{15}{5}$
$y = \frac{1}{5}x + \frac{23}{5}$
$y = \frac{1}{5}x + 4.6$, so y-intercept is $(0, 4.6)$.
