Hi again !
a) A point on the line y=3x-4 has a x-coordinate of 50.
What is the y-coordinate of this point?
I did 3x50-4 and go 146 but I think its wrong!
b) A point on the line y=3x-4 has a y-coordinate of 50.
What is the x-coordinate of this point?
I did 50+4 divided by 3 and got 18 but i think thats wrong too
c) Is the point (-10, -34) on the line y=3x-4? Show how you know
Thankyou to anyone who can explain this to me !
