Solve the following pair of equations graphically. 2x - 3y = -1
0.8 x - 3.5 y = 1/5 (one over 5)

x= - 41/6, y= -6/23

Step-by-step explanation:

2x - 3y= - 1 ...(1)

0.8x - 3.5y=1/5 ...(2)

(2)×10 : 8x - 35y= 2 ... (3)

(1)×4 : 4x-12y= - 4 ...(4)

(3)-(4): 8x-35y=2

8x-12y= -4

- 23y= 6

y= - 6/23

Substitute y= - 6/23 into any equation

Exp : 2x - 3(-6/23) = - 1

2x+18/23 = - 1

2x = - 41/3

x= - 41/6

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.

one set of data has more variation than the other. hope this !
