Damon runs the 100-meter dash at an average speed of 8 meters per second. The equation d=8t describes the distance d that Damon can run in t seconds at this speed. Represent the function by a graph.

## I am trying to get the answer for d=8t

This is just a direct variation equation. Pretend that the t is your x-coordinate and the D is your y-coordinate. If so, then your equation would look like this:

y = 8x

If you remember, slope-intercept form (y=mx+b) allows you to graph linear equations easily. In this case, your equation could look like this:

y = 8x + 0

The slope is 8 and the y-intercept is 0.

Plot the y-intercept first (0.0).

Then use the slope to move from this point to the next. A slope of 8 is the same as 8/1 which means to rise 8 and run 1 (go up 8 and right 1). This will move you to the next point (1,8). Plot this point.

If you connect these two points, then you will have a graph of the function.
