Answer:

(b) No, both are wrong

Explanation:

Compare the given equation to the form ...

y = mx + b

You see that m = 1/3, and b = -1.

b is the y-intercept, the point where the graph crosses the y-axis. In the equation, that value is -1. In the graph shown, that value is +1, so we know the y-intercept is wrong.

__

m is the slope. This is the ratio of "rise" to "run". A slope of 1/3 means the graph goes up 1 unit for each 3 units to the right. The slope of the line on the graph shown is about 3: it rises 3 units for each 1 unit to the right. So, we know the slope is wrong.

__

That is, both the slope and y-intercept of the graphed line are different from those of the given equation. Corey is not correct. The attachment shows a correct graph.
