A line contains the points (0,0) and (1,4). Select all the equations that represent this line.(just plug the points into each equation, but remember, you only want the lines).

You could find a general equation because you have both points, so it takes less time than checking each of the equations. For this, you have to find the tangent line. A line has an equation in the form of y=m*x+n. In this case, n=0 because one of your points is (0,0), which means that 0=0*m+n. You can then find m by using the second point (1,4). you know that 4=m*1, and the only value of m that checks this is 4, so m=4. Replacing in the original formula you get y=4x, which is the 4th option.
