Answer:
The slope of this line is 2.
Step-by-step explanation:
Well, we know that the line is facing upwards, so the slope has to be positive, because it is heading to the right. Now, we simply find two coordinates on the graph on which the line is, and here I will be using (-1, -1) and (1,3). It is much easier if you plot it on the line, and then simply use the rise/run method. This method requires you to have plotted two points on the plane. First, count the units(up or down) it takes for the first point to reach the second(4 in this case), on the y-axis, but you haven't reached yet. Now you need to count from the new y-axis point you had from the last step, and count the number of units(left negative, or right positive) it takes to reach the second point you have on the line(2 in this case). Now you simply divide the change in y(4) by the change in x(2) to get your answer, which is 4.
