Question 1110141: A. Write the equations 8x+5y=120 and 5x-8y=-80 in slope intercept form. B. Determine slope for each equation 8x+5y=120 and 5x-8y=-80 with label. C. Determine algebraically whether the given pair of lines 8x+5y=120 and 5x-8y=-80 are parallel perpendicular or neither by comparing slopes either algebraically (if perpendicular) or numerically (if parallel or neither)
Answer by josgarithmetic(39620) (Show Source): You can put this solution on YOUR website!

The slopes are and .
You can tell by looking at the equations, or if necessary, solving for y in terms of x, and adjust to slope-intercept form.

THIS should tell you something: .
