**1.**The slope of a line whose equation is in slope-intercept form is given by the coefficient of x. The slope is -7.

**2.**The equation can be graphed as is, or it can be put into standard form or slope-intercept form to aid in graphing. Standard form:

x - y = 5. Slope-intercept form:

y = x - 5. Intercept form:

x/5 + y/(-5) = 1.
