Question

Hi guys i need help with this problem y=mx+b

Answer 1

Y = how far up

x = how far along

m = Slope or Gradient (how steep the line is)

b = value of y when x=0

How do you find "m" and "b"?

b is easy: just see where the line crosses the Y axis.
m (the Slope) needs some calculation:
m = Change in Y/change in X
