I’ll explain how to graph them since there are quite a few problems. :)
The easiest way to graph is to first put down the y-axis, which is the end number on the end of the equation. For example, on the first problem the y-intercept is 5, so for this point you would just plot down (0,5).
Next you would just plot down points that follow the slope, which is the first number in the equation, and in the first problem it is 1/2.
The top number determines if you go up and down the bottom number determines where you go right. *only when the slope is negative will you go down for the top part of the slope*
For example, in the first problem you would start plotting from where you put your y-axis and go 1 up and 2 down to plot your next point. You would follow this trend another time or two until you can make your line.
