Question

(18, -19) (1, -19) what is the slope of the line that passes through the two points? options: $-\frac{38}{17}$, zero, $\frac{17}{38}$, -2

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 $(x_1,y_1)=(18,-19)$ and $(x_2,y_2)=(1,-19)$

Step3: Substitute into formula

$m=\frac{-19-(-19)}{1-18}=\frac{0}{-17}$

Step4: Simplify the expression

$m=0$

Answer:

zero
