The graph of a line in the xy-plane has a slope of 1 and contains the point (3,0). The graph of a second line has a slope of −41 and contains the point (−7,0). 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 1 and contains the point (3,0).
