Answer 2

Answer:

$\boxed {\boxed {\sf m= -\frac{2}{7}}}$

Step-by-step explanation:

The slope of a line can be found using the following formula:

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

Where (x₁,y₁) and (x₂,y₂) are the points on the line.

We are given the points (12,7) and (5,9). Therefore:

$x_1=12\\y_1=7\\\\x_2=5 \\y_2=9$

Substitute the values into the formula.

$m=\frac{9-7}{5-12}$

Solve the numerator.

• Subtract 7 from 9
• 9-7=2

$m=\frac{2}{5-12}$

Solve the denominator.

• Subtract 12 from 5
• 5-12= -7

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

This fraction cannot be reduced further, so it is the answer.

The slope of the line is -2/7
