Question

7 (2, 1); (5, 3) $\frac{3-1}{5-2}=\frac{2}{3}$
8 (8, 3); (2, 5)
9 (1, -4); (6, -2)
10 (-3, 1); (-7, 4)
du 0
ab -6
ck $-\frac{3}{5}$
st $-\frac{4}{7}$

Explanation:

Step1: Recall slope formula

Slope $m = \frac{y_2 - y_1}{x_2 - x_1}$

Step2: Calculate for (8,3);(2,5)

$m = \frac{5 - 3}{2 - 8} = \frac{2}{-6} = -\frac{1}{3}$

Step3: Calculate for (1,-4);(6,-2)

$m = \frac{-2 - (-4)}{6 - 1} = \frac{2}{5}$

Step4: Calculate for (-3,1);(-7,4)

$m = \frac{4 - 1}{-7 - (-3)} = \frac{3}{-4} = -\frac{3}{4}$

Answer:

1. $\frac{2}{3}$
2. $-\frac{1}{3}$
3. $\frac{2}{5}$
4. $-\frac{3}{4}$
