Answer:
Step-by-step explanation:
The solution to a system of equations by graphing is found by graphing both equations on a coordinate plane. The solution is the point at which the lines intersect.
<u>First, put both equations in slope-intercept form:</u>
y = x + 4 Already in slope-intercept form
x - y = 1 Isolate y.
-y = -x + 1 Multiply both sides by -1.
y = x - 1
<u>Next, graph both lines:</u>
(See attachment)
In this situation, the lines don't intersect, meaning there is no solution to this system.
