Answer:
(-1, 2)
Step-by-step explanation:
The ordered pair that gives the coordinates of the point where the lines cross is the solution. The horizontal position of that point (-1) is the first number of the pair. The vertical position of that point (2) is the second number of the pair.

A lunette is a semi-circle, which means that it is one half of a circle. To find its area, we can find the area of the whole circle and divide it by two.
Area of a circle: A = pi x r^2
r = 40 / 2 = 20
A = pi x 20^2
A = 400pi / 2 = 200pi
200pi = 628.32
The area of the lunette is approximately 628 in^2.
Hope this helps!! :)
Subtract 2m from both sides : 4m + 3 = -2
Subtract 3 from both sides : 4m = -1
Divide by 4 on both sides : m = -1/4
