Question

7. Choose the graph below that best represents the equation: x-y = -2

Answer 1

Answer: it is graph A

Explanation:

It is pretty easy to tell when x-y= -2

Let's say x is 0 then we have left is -y=-2

So y= 2

And we have [0,2] so graph A is correct

Answer 2

Answer: B

Explanation:

First, we will turn this equation into slope-intercept form as it is easier to view in terms of a graph.

Given:

x - y = 2

Add y and subtract 2 from both sides of the equation:

y = x - 2

We can see that this equation has a y-intercept of -2, so it must intercept the graph at (0, -2). The answer option that meets these requirements is B.
