Question

question 1 8 pts determine whether the lines slope is positive, negative, zero, or undefined. positive undefined slope zero negative

Explanation:

Step1: Recall slope formula

The slope $m$ of a line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is $m=\frac{y_2 - y_1}{x_2 - x_1}$.

Step2: Analyze horizontal line

For a horizontal line, $y_1=y_2$ for any two points on the line. So $m=\frac{y_2 - y_1}{x_2 - x_1}=\frac{0}{x_2 - x_1}=0$ (where $x_2
eq x_1$).

Answer:

zero
