Question
graphing an equation in slope-intercept form
graph ( y = \frac{3}{4}x + 5 )
click or tap the graph to plot a point
Step1: Identify slope and intercept
The equation $y = \frac{3}{4}x + 5$ is in slope-intercept form $y=mx+b$, where slope $m=\frac{3}{4}$ and y-intercept $b=5$. This gives the first point $(0, 5)$.
Step2: Find second point using slope
Slope $\frac{3}{4}$ means $\frac{\text{rise}}{\text{run}} = \frac{3}{4}$. From $(0,5)$, move 4 right (run) and 3 up (rise): $x=0+4=4$, $y=5+3=8$. This gives the point $(4, 8)$.
Step3: Find third point (optional check)
From $(0,5)$, move 4 left and 3 down: $x=0-4=-4$, $y=5-3=2$. This gives the point $(-4, 2)$.

Table of points:
| $x$ | $y$ |
|---|---|
| $0$ | $5$ |
| $4$ | $8$ |
To graph: Plot the points $(-4,2)$, $(0,5)$, and $(4,8)$, then draw a straight line through them.
