-4y = 8x

Divide both sides by -4

y = -2x

This is in the form of y = kx, where k is the constant of variation.
y = kx is the direct

That means, k = -2.

The constant of variation is B. -2.

(2,8),(7,8) slope of the line

aliina [53]

Answer:

The slope of line is 0 given points (2,8)(7,8)

Step-by-step explanation:

We need to find slope of line given points (2,8),(7,8)

The formula used to find slope of line is: $Slope=\frac{y_2-y_1}{x_2-x_1}$

We are given:

$x_1=2, y_1=8, x_2=7 \ and \ y_2=8$

Finding slope using formula:

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{8-8}{7-2}\\Slope=\frac{0}{5}\\Slope=0$

So, the slope of line is 0
