Draw dots on the graph to represent these. The slope will be the same for a straight line no matter which two points you pick as you know. We get slope by dividing the diffference of coordinates on the vertical axis y by the difference of the coordinates on the horizontal axis x.
Im going to show you some of them which is going to be the most used.
To find the slope you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. You can easily calculate the slope of a line using the coordinates of two of its points. The slope is 24 which of course you can simplify to ½.
