In the coordinate plane, Line A has a slope of -2 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 correct choice from the following:	A) 0	B) 1	C) 2	D) 3	E) 4
The equation of Line A is y = -2x + 4   The equation of Line B is y = 5x - 10   5x - 10 = -2x + 4   x = 2   y -2  + 4=
