At what value of x do the graphs of the equations below intersect 2x-y=6 5x+10y=-10
1 answer:
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

The fourth coordinate point would be at (1, 1). If you look at the graph, it's easy to see which point is missing. You can also tell by looking for the x and y values that don't repeat, since this is a rectangle. -6 is an x-value for two coordinate points, but 1 is an x-value for only one. 10 repeats as a y-value in two coordinate points, but 1 only appears once.
