Hello! Your figures are missing, so I could help you in a general way. The Slope-intercept form of the equation of a line is given by the form:
Case 1:
If the slope is positive, we will have a line as the form illustrated in figure 1. So as x increases y also increases.
Case 2:
If the slope is negative, we will have a line as the form illustrated in figure 2. So as x increases y decreases.
Case 3:
If the slope is zero, we will have a line as the form illustrated in figure 3. here we have a constant function.
Case 4:
m: undefined
If the slope is undefined, we will have a line as the form illustrated in figure 4.
