Which system matches the graph below? y = -4 x and y = 2 x - 3 y = -4 x and y = 2 x + 3 y = 4 x and y = 2 x - 3 y = -4 -x and y = 2 x - 3

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

1/3 + 1/5 = 8/15.

step-by-step explanation:

hope it

5+2x=a
