In the coordinate plane, Line A has a slope of -1 and an x-intercept of 2. Line B has a slope of 5 and a y-intercept of -10. If the two lines intersect at the point (a,b), what is the sum a+b?	Choose the most appropriate option
A) 0 B) 1 C) 2 D) 3 E) 4
The equation of Line A is y = -x + 2   The equation of Line B is y = 5x - 10   5x - 10 = -x + 2   x = 2   y = 0   The point of intersection is (2,0) and then a+b = 2.   The answer is 2.
