Graph the relation y = -2x + 3 for integer values of x from 0 to 4.

You know this is an equation of a linear function, so the dots you graph will be in a straight line. However, you are not asked to draw the whole line, just put a dot on the graph for each input/output combination. So, if x = 0, find y and plot that point. If x = 1, find y and plot that point, and so on. Which graph matches your results?

Describe the relationship between the input (x) and output (y) values in this graph.

• When x increases by 1, y increases by 7.

• When x increases by 1, y increases by 5.

• When x increases by 1, y increases by 2.

• When x increases by 2, y decreases by 5.
