Question

line a is a straight line that passes through the origin. select any two points shown on line a to draw a slope triangle. the line decreases from left to right. therefore, the slope is negative. enter the slope of line a:

Explanation:

Step1: Recall slope - formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$, where $(x_1,y_1)$ and $(x_2,y_2)$ are two points on the line.

Step2: Select two points

Let's take the origin $(0,0)$ and another point on the line, say $(3,3)$.

Step3: Calculate the slope

$m=\frac{3 - 0}{3 - 0}=1$
