Answer:
(4, 12)
Step-by-step explanation:
Hello!
Since two of the equations are linear we can use those to find where all three intersect
The two linear equations are y = 2x+4 and y = x+8
We know this because they do not have a square value and they are in slope intercept form which is linear.
Since y is equal to both of them that means they are equal to each other
2x + 4 = x + 8
We can now solve it algebraically
Subtract x from both sides
x + 4 = 8
Subtract 4 from both sides
x = 4
We now have the x coordinate
To find y we put the x coordinate into either of the two original equations and solve to y
y = 4 + 8
y = 12
We now know the point is (4, 12)
The answer is (4, 12)
Hope this helps!
