Today we learned two new things. First, we learned how to write an equation or rule for a line given 2 points. The steps for doing this are the following.
1. Find the slope.
2. Using the slope and a point find the y-intercept.
3. Rewrite the equation in slope-intercept form, replacing m and b.
The second thing we learned was how to draw a trend line and write and equation for that trend line. We can use the trend line to estimate information on the graph.
