Question

The value of "y" varies directly with "x" and

y = -8 when x = 20.
Find "y" if x = -4.
Now use the value you found for k, in y=kx to
solve for y when x is -4.
k=-²/
y =
Reduce to simplest form.

Answer 1

y = 8/5

Explanation:

Formula we use,

→ y = kx

Then the value of y will be,

→ y = kx

→ y = (-2/5) × (-4)

→ y = (-2 × -4)/5

→ [ y = 8/5 ]

Hence, the value of y is 8/5.
