From the table, y varies directly as x. Therefore, the constant of variation is k = 2 and y = 2x.

<h3>How to find a direct variation?</h3>

For direct variation,

y ∝ x

Therefore,

y = kx

where

k = constant of proportionality

Hence,

(-2, -4)

-4 = -2k

k = -4 / -2

k = 2

(-4, -8)

y = -4(2) = -8

Therefore,

k = 2 and y = 2x

Write an equation in point-slope form and in slope-intercept form.

SpyIntel [72]

The point-slope form:

$y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (1, -5) and (-3, 7). Substitute:

$m=\dfrac{7-(-5)}{-3-1}=\dfrac{12}{-4}=-3\\\\y-(-5)=-3(x-1)\\\\\boxed{y+5=-3(x-1)}$

The slope-intercept form:

$y=mx+b$

$y+5=-3(x-1)$ use distributive property

$y+5=-3x+3$ subtract 5 from both sides

$\boxed{y=-3x-2}$
