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

Step-by-step explanation:

Step 1: Define

Point (3, 4)

Point (4, 8)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

1. Substitute [SF]:                    $m=\frac{8-4}{4-3}$
2. Subtract:                              $m=\frac{4}{1}$
3. Divide:                                 $m=4$

Answer 2

Answer:

m = 4

Step-by-step explanation:

$m=\frac{rise}{run}=\frac{8-4}{4-3}=\frac{4}{1} =\boxed{4}$

Hope this helps.
