In the coordinate plane, Line A has a slope of -1 and an x-intercept of 1. Line B has a slope of 3 and a y-intercept of -3. If the two lines intersect at the point (a,b), what is the sum a+b? Choose the correct choice.
A) 0	B) 1	C) 2	D) 3	E) 4
The equation of Line A is y = -x + 1   The equation of Line B is y = 3x - 3   3x - 3 = -x + 1   x = 1   y = 0   The point of intersection is (1,0) and then a+b = 1.   The answer is 1.
