C + P = 6
C = -P + 6

750P + 1425C = 7200
750P + 1425(-P + 6) = 7200
750P - 1425P + 8550 = 7200
-675P = -1350
P = 2

C + 2 = 6
C = 4

Graph the system of equations.<br><br> {2x - y =4<br> {x - y = -2
Mnenie [13.5K]

Answer:

See attachment

Step-by-step explanation:

The given system is

2x-y=4

x-y=-2

We write the system in slope-intercept form:

y=2x-4

y=x+2

The first equation has slope of 2 and y-intercept at (0,-4)

When y=0, x=2.

We plot (0,-4) and (2,0) to graph this first equation.

The second equation has a slope of 1 and a y-intercept at (0,2)

Also when y=0, x=-2.

We plot (0,2) and (-2,0) and draw a straight line through them.

The graph of the system is shown in the attachment.
