The given equations are in standard form, first, write them in slope-intercept form.
"p" is the variable in the x-axis
"g" is the variable in the y-axis
First equation
Second equation
Next, you have to determine two points for each equation, the easiest point to determine is the y-intercept, just replace the formula with p=0
For the second point, you can choose any value of p, for example, p=10
First equation
For p=0
The first point is (0,48)
For p=10
The second point is (10,28)
Plot the points and link them with a line.
Second equation
For p=0
The first point is (0,60)
For p=10
The second point is (10,30)
Plot both points and link them to determine the line
