160, I think. SA=2(lw+lh+wh).
Slope-intercept form:
y=mx+b
m=slope
b=y-intercept
Data:
m=4/5
b=-1
y=mx+b
y=(4/5)x-1
Answer: the equation of the line with slope=4/5, and y-intercept=-1 would be:
y=(4/5)x-1
The possible x-values of the equation are options C and F. These are the + and - values that make the equation true.
