Question

Write an equation that gives the proportional relationship of the graph.

Answer 1

Answer:

B) y = 7x

Step-by-step explanation:

Start with:

$m=\frac{y_2-y_1}{x_2-x_1}$

Substitute in two points from the graph.

(Let's use (8,56) & (16,112)

$m=\frac{112-56}{16-8}$

Combine like terms.

$m=\frac{56}{8}$

Simplify.

$m=7x$

Answer 2

Answer:

y = 7x

Step-by-step explanation:

We need to find the slope

We have two points (0,0) and (8,56)

m = (y2-y1)/(x2-x1)

   = (56-0)/( 8-0)

  = 56/8

  = 7

The proportional relationship is

y= kx where k is the slope

y = 7x
