Answer:
(-3,5)
Step-by-step explanation:
x = - 3
y = 5
x + y =2
x - y = -8
Cancel out both y's. Add x's and whole numbers to find x.
2x = - 6
Divide.
Insert - 3 into one of the equations. Solve for y.
- 3 + y = 2
Cancel out - 3 by adding 3 to both sides.
y = 2 + 3
Simplify.
Statement D. is true
(-2, 11/2)
use the mid-point formula!
((x1+x2)/2, (y1+y2)/2)
((-1+-3)/2, (-1+12)/2)
Answer: y=4x-1
Step-by-step explanation: the line goes through (-2,7) and is perpendicular to the line x-4y =24
