Question

Find the slope of the line.

Answer 1

Answer:

$slope = \frac{4}{5}$

Step-by-step explanation:

slope formula:

$\frac{y2 - y1}{x2 - x1}$

use the two coordinates given in the graph to find the values

i) (10, 6)

x1 = 10

y1 = 6

ii) (4, 1.2)

x2 = 4

y2 = 1.2

substitute the values into the formula

$\frac{1.2 - 6}{4 - 10}$

$\frac{ - 4.8}{ - 6}$

$\frac{4}{5}$

Answer 2

Answer:

$\displaystyle m=0.8$

1. Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (4, 1.2)

Point (10, 6)

Step 2: Find slope m

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

1. Substitute [SF]:                    $\displaystyle m=\frac{6-1.2}{10-4}$
2. Subtract:                              $\displaystyle m=\frac{4.8}{6}$
3. Divide:                                 $\displaystyle m=0.8$
