Question

Solve the systems by graphing.

Y=1/2 x-5
y=-X+4

Answer 1

Answer: (6, -2)

Explanation:

First, we will graph these equations. See attached. One has a y-intercept of -5 and then moves 2 units right for every unit up (we get this from the slope of 1/2). The other has a y-intercept of 4, and moves right one unit for every unit down (we get this from the slope of -1).

The point of intersection is the solution, this is the point at which both graphed lines cross each other. Our solution is:

(6, -2) x = 6, y = -2
