On a coordinate plane, 2 lines intersect at one point. The graph shows the solution of a system of equations. How many solutions does it have?

Exactly one solution

Step-by-step explanation:

In a system of equations, the intersection points are where the solutions are.

Since there is only one intersection point in this system, this means that there is only one solution, which is at that exact point.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
