If you mean: 2x-9y = 14 and x-6y = 7 then it works out x = 7 and y = 0

The equation y = 7x represents a linear relationship where the value of y is always 7 times the value of x. Therefore, all ordered pairs for this equation will have y as a multiple of 7x. For example, when x = 1, y = 7; when x = 2, y = 14; and so on. The ordered pairs for y = 7x will be in the form (x, 7x).
There are many different ordered pairs for this. To figure it out, make up a value for x. Then plug it into the equation and solve to find y. You can use any number. For example, if x=2, then your equation would be 3(2)+1. Solve that and you get 7 for the answer (y). if x=2, then y=7 so one of the ordered pairs would be (2,7).
(-4 -2) (0 -3) (2 7) (1 4)
there is an infinte amount of ordered pairs in this equation a few examples could be... (1,-3) (2,-13) (3,-23) (234652,-2346513) (-25,257)
In general to work out the slope it is: (y1-y2)/(x1-x2) whereas x and y are a pair pf coordinates
