28 / 4 will get the unit rate for dress shirts but you have to tell the costs of the pairs of pants
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cutoff point with the y axis
We find the slope with the given points:

Thus, the line is given by:

We substitute a point to find "b":

Finally, the equation is:
