Here is my INB page on Slope.
It contains a foldable that has students solve for the slope 4 ways: slope formula, change in y over change in x (table and points), rise over run (graph) and subtracting the points.
The Flip book contain the definition of slope, the different kinds, the y-intercept in a table, graph, and equation and finally and explanation of each variable in y=mx+b.
There is also 9 task cards to end the lesson where students are asked to find the slope from a set of points, a table,a graph and an equation. They are also asked to describe what the y-intercept is, the slope, and what they look like in a graph.
