Question

Line PR passes through the origin and (-20, 8). Coordinate point Q is also on the line. What is the slope of the line PQ?

Answer 1

The slope of line PQ is -0.4.

Step-by-step explanation:

To find the slope of the line PQ, we need to calculate the difference in the y-coordinates divided by the difference in the x-coordinates of the two points.

The coordinates of P and Q are (0,0) and (-20,8) respectively.

Slope = (change in y-coordinates)/(change in x-coordinates) = (8-0)/(-20-0) = 8/-20 = -0.4

So, the slope of line PQ is -0.4.
