Given:
An increase of 5 units in t corresponds to an increase of 2 units in d.
Here t is the x-axis, while d is the y-axis.
Let's graph the line:
Here we are told there is a proportional relationship. this means the line must pass through the origin of the graph
Here are the steps:
Plot a dot at (0, 0)
Move 1 unit to the right, (you will now be at point (1, 0)
Now move 5 units upward, Now you'll be at point (1, 5)
Next is to draw a straight line through the points: (0, 0) and (1, 5)
Now the rate of change will be the slope,
