For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have two points through which the line passes, so we can find the slope:

Thus, the equation is of the form:

We substitute one of the points and find "b":

Finally, the equation is of the form:

Answer:
Ratio of sweaters to dresses = 8 : 5
Sum of ratios = 13
Let number of sweater + dresses = x


The answer would be 150 as each ten bar is si worth 10 and 10x15=150.
