y= x-4: gradient is 1 ; y- intercept is -4
g= -3+6
g= 3: y-intercept is 3; gradient is 0
Then you graph it
After graphing it you should find the intersection of this two line which I marked on the graph.
I’m not sure if the question is just asking you to show how these two functions are expressed on a graph or does it actually ask you to find the intersection of the two lines
But yea the coordinates of the intersection is (7,3)
