# What information do you need to create a linear model?

Feb 17, 2015

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 $\left(s l o p e = \frac{\Delta y}{\Delta x}\right)$ to find the slope, and then plug the slope and any one of your coordinate pairs into the slope-intercept formula $\left(y = m x + b\right)$ 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 :)
