(7) Line is passing through two points (2,-5) and (-3,0), and Line 12 is the graph of the equaion x-y=7. Are they parallel to each other? perpendicular to each other? or neither? Show necessary work. (7) (8) Line l is the graph of 3x + y = 1, and Line 12 is passing through (-6, 1) and perpendicular to l. Write the equation of 12 in the Slope-intercept form. Show necessary work. (8)
