Explanation: I hope this helps you with your stuff.
By looking at the picture there are 75 yards above water and 75 yards under water. To find the total distance of the lake you add 75 and 75 and you get 150 as you final answer!
The equation for these lines to pass through the points are; y= 3/2x -3
A and c are parallel to each other and b is perpendicular to both a and c.
7 and 6 are parallel was that the answer you were looking for?
