Question

How do you graph `y=x-2`?

Answer 1

Method of 'How' to graph is described in Explanation

Explanation:

You asked `" "underline("'How")" do you graph.."`

This is a strait line graph. In theory you only need to calculate 2 points and draw a line through them. I would suggest that 3 is better. If all 3 line up then you are very likely correct with your calculations. If they do not line up then check you numbers. You have gone wrong some where!

`"Chosen values for x -> -3 1 4"`
`underline("Subtract -2 -2 -2")`
`"resulting value of y -5 -1 2"`

Project the x-values upwards. Project the y-values horizontally. Where they meet is the plotted point. Put a dot there.

Line all the dots up with a ruler and draw your line.
