I am given;
y = 1/2x + 3
I am asked to produce a table of data. I have no problem working this out, however I can't see where the value 1/2 originates from?
So if I am asked in a different question to work out the equation of the line, and given (-4. -2) and (2, 7) I can put the table together, but y = ? to multiply the values.
How do I work this out ?
