Question

30 POINTS!!!!!!!!!!! ONLY ANSWER IF 100% SURE

Estimate the solution to the following system of equations by graphing.

-4x + 5y = 8
6x - y = 11

A.
`(-(5)/(2),-(7)/(2))`
B.
`((1)/(2),(3)/(2))`
C.
`((5)/(2),(7)/(2))`
D.
`(-(4)/(3),(8)/(3) )`

Answer 1

the answer is C

Explanation:

the lines lie at 2.5, 3.5

5/2= 2.5

7/2=3.5

and since they are not negative numbers it would not be answer A

Answer 2

C.(2.5,3.5)

Explanation:

Graphing both equations, we can see where they cross

The x coordinate is about 2.5 and the y coordinate is about 3.5
