Answer 1

Do you know how to substitute in equations? :)

Answer 2

no

Answer 3

Okay, so you have (x,y) coordinates. When you replace the x-variable with the x-coordinate and the y-variable with the y-coordinate, you've substituted an equation. Thing you can do that with choice 1?

Answer 4

oh okay i see now thanks

Answer 5
