what does the solution of (-2,-5) for the system of equations 9x-8y=22 and -10x + 5y= -5 indicate on the coordinate plane?
1 answer:
Answer:
see the explanation
Step-by-step explanation:
we have
----> equation A
---> equation B
we know that
The solution of the system of equations by graphing is the intersection point both graphs
The solution of the system is the point (-2,-5)
therefore
The point (-2,-5) indicate on the coordinate plane the intersection point both lines ( a common point for both lines)

Answer: B
You can find slope by using the slope formula. Because we are already given two coordinate points, we can use that to find our slope. The slope formula is . This also refers to
or 10/-4 or -5/2. Any coordinate with the x-value as 0 means that that coordinate is the y-intercept. Because (0,5) has 0 as its x-value, the y-intercept is 5.
