Answer:
If you were look for the cords for the blue one. It will be (-5,4) for O (-2,1) for W and (-7,-3) for N
If it was for the Green one. It will be (-5,-2) for 'O (-1,-2) for 'W and (-5,-7) for 'N

Answer:
It is the branch of math that is in charge of dealing with letters known as variables.
Step-by-step explanation:
These variables are used to fill in the place of missing numbers in an equation or solution.Algebra is widely used all over the world in schools.
Solution is where the lines intersect. It's is (-2 , 1)
Answer is B.(-2,1)
<span>To solve this problem, we can use this formula d = rd (distance = rates x time)
She runs at a speed of 9 mph and walks at a speed of 3 mph.
Her distance running is
d = 9tr
where tr is the time she spends running
Her distance walking is
d = 3tw
where tw is the time she spends walking
The distances are the same so
9tr = 3tw
We also know that the total time is 5 hours
tr + tw = 5
tr = 5-tw
Substitute this value of tr in the first equation
9tr = 3tw
9(5-tw) = 3tw
45-9tw = 3tw
45 = 12tw
3.75= tw
Denise will spend 3.75 hours (3 hours, 45 minutes) walking back and 1.25 hours (1 hour, 15 minutes) running.</span>
