Question

Is (-3,-9) a solution to the equation y = 3x?

Answer 1

do you know which is the x and y coordinates in (-3,-9)?

Answer 2

noo

Answer 3

okay..here's a hint

an ordered pair is in the form (x,y)

so if you have something like (1,2) the x coordinate is 1 and the y coordinate is 2

so can you identify which are the x and y coordinates in (-3,-9)?

Answer 4

yes absolutely, to find it, put yhe value of x-cordinate in the equation, if you find the y- cordinate as the answer, your answer is right ;)
