If y varies directly as x, and y = -4 when x= 2, find y when x= -6

Y = 12

Step-by-step explanation:

Y varies ditectly as x

Y = kx

When y = -4, x = 2

Substitute the value of x and y into Y = kx

-4 = k * 2

Make k the subject of the formula

k = -4/2

k = -2

:. The equation connecting Y and x is

Y = -2x

When x = -6

Y = -6*-2

Y = 12

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
