Answer:
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.
