Answer:

Bottom right

Explanation:

The equation is y = 2x - 3

2 represents the slope

-3 represents the y-intercept

The y-intercept is when x = 0

So first, we look at the graphs and find the graphs that display when x = 0, y = -3 aka (0, -3)

From this, we can deduce the two graphs on the left side are wrong

It must be the two on the right

Now we figure out which one has a slope of 2 aka rise over run = 2/1

Which graph goes up (rises) 2 units and goes forward (runs) 1 unit?

The top right graph depicts a slope of 1/2, not 2/1 so this is incorrect

The bottom right graph displays a slope of 2/1 aka 2

Bottom right graph is the correct answer
