#### Answer:

x-intercept = 4

y-intercept = -4

Slope = 1

#### Explanation:

To find all of these, we use slope-intercept form, y = mx + b. An intercept is when the line crosses an axis. Your question already assumes when y = 0, so if we solve for x we get

x = 4

Which is our x-intercept. If we put in y for 0, we get x - 4 = y, and if we change x to 0, we can find where the line crosses the x-axis.

y = -4

Lastly for slope we look at the coefficient in front of x, which since there is not one shown, it is actually 1x. This gives us

Slope = 1.
