Find the slope easy giving brainlest

Korvikt [17]

Answer:

Problem 20: $m$ = $2$

Problem 21: $m$ = $-2$

Problem 22: $m$ = $1$

Problem 23: $m$ = $3$

Step-by-step explanation:

The formula to find the slope of a line: $m = \frac{y_{2} - y_{1}}{x_{2}-x_{1}}$ .

Problem 20:

1) Substitute the values into the formula and solve it.

$m$ = $\frac{3-7}{2-4}$

$m$ = $\frac{-4}{-2}$

$m$ = $2$

Problem 21:

1) Substitute the values into the formula and solve it.

$m$ = $\frac{-5-1}{2--1}$

$m$ = $\frac{-6}{3}$

$m$ = $-2$

Problem 22:

1) Substitute the values into the formula and solve it.

$m$ = $\frac{3-7}{-6--2}$

$m$ = $\frac{-4}{-4}$

$m$ = $1$

Problem 23:

1) Substitute the values into the formula and solve it.

$m$ = $\frac{-4-2}{-4--2}$

$m$ = $\frac{-6}{-2}$

$m$ = $3$

*Extra*: The equation of a line is written in this form: $y = mx+b$ , where $m$ is the slope and $b$ is $y$ -intercept
