The graph of a line in the xy-plane has a slope of and contains the point (1,−5). The graph of a second line passes through the points (0,4) and (12,0). If the two lines intersect at the point (a,b) what is the value of a−b? Get tutor helpThe graph of a line in the xy-plane has a slope of 4 and contains the point (1,−5).
