what is the slope of the line that passes through the points $(-9, 0)$ and $(-17, 4)$? write your answer in simplest form.
Answer
Explanation:
Step1: Recall slope formula
The slope $m$ between two points $(x_1,y_1)$ and $(x_2,y_2)$ is $m=\frac{y_2-y_1}{x_2-x_1}$
Step2: Assign point values
Let $(x_1,y_1)=(-9,0)$ and $(x_2,y_2)=(-17,4)$
Step3: Substitute into formula
$m=\frac{4-0}{-17-(-9)}$
Step4: Simplify numerator and denominator
$m=\frac{4}{-17+9}=\frac{4}{-8}$
Step5: Reduce fraction to simplest form
$m=-\frac{1}{2}$
Answer:
$-\frac{1}{2}$
