Question

What information do you need to create a linear model?

Answer 1

You could create a linear model with at least either of the following pieces of information:

• Two data points

• One data point and a slope.

For the first part, you'd be able to find the model by first finding the slope using the slope formula `(slope = (Deltay)/(Deltax))` to find the slope, and then plug the slope and any one of your coordinate pairs into the slope-intercept formula `(y=mx+b)` and solve for `b` (your `y` intercept).

For the second part, it's pretty much the same thing as part one, except you don't need to find the slope.

Hope that helped :)
