Question

go
find the slope of each line.
15.
slope:
16.
slope:
17.
slope:

Explanation:

Step1: Pick two points for line 15

Choose $(0,0)$ and $(6,8)$

Step2: Calculate slope for line15

Slope formula: $m=\frac{y_2-y_1}{x_2-x_1}$
$m=\frac{8-0}{6-0}=\frac{8}{6}=\frac{4}{3}$

Step3: Pick two points for line 16

Choose $(0,3)$ and $(12,0)$

Step4: Calculate slope for line16

$m=\frac{0-3}{12-0}=\frac{-3}{12}=-\frac{1}{4}$

Step5: Pick two points for line 17

Choose $(1,6)$ and $(7,0)$

Step6: Calculate slope for line17

$m=\frac{0-6}{7-1}=\frac{-6}{6}=-1$

Answer:

1. Slope: $\frac{4}{3}$
2. Slope: $-\frac{1}{4}$
3. Slope: $-1$
