Question

How do you find slopes of two points for example (9, 6) and (4, 4)?

Answer 1

Answer:

$m = \frac{2}{5}$

Step-by-step explanation:

Slope is equal to the change in y over the change in x, or rise over run.

$m = \frac{change \: in \: y}{cahnge \: in \: x}$

The change in x is equal to the difference in x-coordinates  and the change in y is equal to the difference in y-coordinates.

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

Substitute in the values of x and y into the equation to find the slope.

$m = \frac{4 - (6)}{4 - (9)}$

Simplify.

$m = \frac{2}{5}$

Therefor, the answer is m = 2/5.

Answer 2

Answer:

$\frac{2}{5}$

Step-by-step explanation:

Use the following equation:

slope (m) = $\frac{y_2 - y_1}{x_2 - x_1}$

Let:

$(x_1 , y_1) = (4 , 4)\\(x_2 , y_2) = (9 , 6)$

Plug in the corresponding numbers to the corresponding variables:

m = $\frac{6 - 4}{9 - 4} = \frac{2}{5}$

$\frac{2}{5}$ is your slope.
