Greater unit rate: function 1. Greater y-intercept: function 2.

Step-by-step explanation:

The unit rate of a function is its rate of change, and it is given by

where is the change in the y-variable and the change in the x-variable.

For function 1, the rate of change is:

For function 2, we can use two points taken from the graph; let's take

(-4,0) and (0,6)

So its rate of change is

So, function 1 has the greater unit rate.

The y-intercept of a function is the y-coordinate of the point where the function touches the y-axis, so the point at which x = 0.

For function 1, this point is already given: in fact, it is

x = 0, y = 5

So the y-intercept is 5.

For function 2, the y-intercept can be inferred from the graph: we see that at x = 0, y = 6, so the y-intercept is 6.

Therefore, function 2 has the greater y-intercept.
