Question

What is the slope of the line?

Answer 1

-3

Explanation:

slope = rise/run

rise = vertical distance

run = horizontal distance

Step 1. Find two easy to read points on the line. Use points on intersections of grid lines.

For example, choose points (0, -3) and (-1, 0).

Step 2. Start at one point, say (0, -3). We must go to the other point using only vertical and horizontal moves. Go up 3 units. That is a rise of +3. It's positive 3 since up is positive. Now go left 1 unit. That is a run of -1. It is negative because going left is negative.

Step 3.

slope = rise/run

slope = 3/(-1) = -3

Answer: slope = -3

Answer 2

-3

Explanation:

First, you look at which way it is going. From left to right, the line is going down, so the slope is negative. Change in y is 3 and change in x is 1. From any two points on the line, the y value changes by 3 every time the x value changes by 1.
