How do I graph this then find the solution?

the solution is (3,4). x = 3, y=4

Step-by-step explanation:

First, we refer to y = mx + b, where m is the gradient and b is the y-intercept. You can plug in any values of x to find values of y and plot them.

For the solution, you can equate the two equations. y1=y2 ; -x + 7 = x + 1, work from there to find the x which is 3 in this case. Then, substitute x=3 into one of the equations to get y = 4. That's the point where the two equations intersect with each other.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

yes   because as the functions are graphed they eventually will intersect unless otherwise
