Explanation:

Find the slope of AB

: The slope is


(7 - 0)/(3 - 8) = - (7)/(5)

Find the y intercept by plugging coordinates in


0 = - ( 7)/(5) (8) + b


0 = ( - 56)/(5) + b


b = (56)/(5)

Find CD: We know that AB and CD are parallel to each other so this means they both have the same slope.

We can find the next point by subtracting 7 from the y coordinate of Point D, Adding 5 to the x coordinate of Point D.

Point C=(10,-2).

Find the y intercept by a plugging coordinates in


5 = - (7)/(5) (5) + b


5 = - 7 + b


12 = b

So the Equation of Line CD is


- (7)/(5) x + 12
