SOLUTION: solve by graphing and find the two coordinate pair as a solution of the two equations below: X-Y=-4 2y+X=5 P.S.- the coordinate pair as the solution must be the same for both e

Question 179519: solve by graphing and find the two coordinate pair as a solution of the two equations below:
X-Y=-4
2y+X=5
P.S.- the coordinate pair as the solution must be the same for both equations

Switch both to slope-intercept form and graph.
1.
1.
Slope = 1, Y-intercept=(0,4)
Another point on the line: (-4,0)

Slope= -1/2, Y-intercept=(0,5/2)
Another point on the line (5,0)

Grpah the points and connect the lines.
Look for the intersection point of the two lines.

Looks like the intersection occurs at (-1,3).
Check the solution in both equations.

The intersection point (1,3) leads to two true statements.
It is a good solution.
