What are the dimensions of the rectangle shown on the coordinate plane? On a coordinate plane, a rectangle has points (1, negative 1), (10, negative 1), (10, negative 5), (1, negative 5).

the dimensions are length 8 units by width 4 units

Step-by-step explanation:

The rough graphical sketch diagram is shown in the image below. Scale is multiples of two.

the least common denominator is 40

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
