So when I plotted the points previously and checked my answer it said that it was incorrect and that I had to plot the point containing the y intercept which is 5 and then use the slope and plot a second point. What does that mean and how do I do that?

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

it would be:

c.parallelogram.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

answer: idk
