Today Carson and I continued with our review of linear functions. We reviewed what we did last class on the different ways to find a slope, write the equation of a line, and graph a line. Today we started by writing the equation of a line passing through two points. Carson recalled to find the slope first with the formula. Then he was stuck. So I showed him the parts of the slope intercept form of a line and how we know the x and y values. He realized he could substitute those in, to find the y-intercept and correctly write the equation of a line. We practiced this with a few examples. Next we saw what happens when the slope is 0 or undefined. We discussed how these would produce horizontal and vertical lines, so their equations won't look like y=mx+b. It will just be x=Number or y=Number.
