Equivalent linear algebraic expressions

## Graphical explanation

#### Solution

If you sketch the linear graphs with **equations** y = 2 − 3t and y = −3t + 2 you will get the same line. They both have a y-intercept of 2 and a gradient of −3.

Hence 2 − 3t is equivalent to −3t + 2.

The graphs of y = 2 − 3t and y = −3t + 2 are shown below.
