Slope-intercept equation from two solutions

The topic  appears under the 8th Grade Math Mission. This exercise expands the knowledge of graphing lines and how to form linear equations.

Types of Problems
There are types of problems in this exercise:
 * 1) Graphing lines from given points: You are given two points on a line and told to find the equation of that line in slope intercept form (y=mx+b)
 * 2) Graphing lines from given points with a graph: This type of problem is exactly like the first, except you are given a graph of the line as well.

Strategies
To complete this exercise the main thing to keep in mind is that using the equation y=mx+b is key to be able to graph lines easily.
 * 1) Remember to use the formula m=(y2−y1)/(x2−x1) when forming an equation when given two points on a line.
 * 2) When entering answers in a textbox, pressing enter on the keyboard will submit the answer more quickly than clicking a mouse button.
 * 3) Use the graphs given in some problems for help in visualizing what your line should look like.
