Answer:
The graphs of the equations intersect at x=2
Step-by-step explanation:
we have
----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system of equations is the intersection point both lines
Using a graphing tool
The solution is the point (2,-2)
see the attached figure
therefore
The graphs of the equations intersect at x=2
Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
