Slope is the proportional relationship between the amount that the y and x coordinates increase. It is typically used to determine the steepness of a line.
You can find the slope by solving the following equation:
Using this equation, plug in your x and y values accordingly to find the slope with ease.
But wait, how do you find the x and y values? Well there's 2 ways.
Method 1: If you have a table...
Find two sets of values in your table. Typically, you choose the first one and the second one. Then, plug the values into the equation. The second set will be x2 and y2 values, and x1 and y1 for the first set.
Method 2: If you have a graph...
Find two points on the graph that align with whole numbers on the graph. Then, calculate the distance of the 2 points. Your rise, which is the y coordinate, goes on top, and the run, which is the x value, goes on right.
You can graph a slope by graphing the points on a graph, and then drawing a straight line that goes through both points.
