Determine whether the graph represents a proportional or non-proportional relationship. Then select the correct equation in the form y=mx or y=mx+b to represent the relationship between the independent and dependent quantities. This graph is an example of a blank area relationship. The equation that represents the relationship between the independent and dependent quantities is blank area.

Unproportional
Proportional
y=5x+20
y=60x
y=x+30

Non-proportional

y =

Step-by-step explanation:

If a line doesn't pass through the origin relationship represented by the line is non proportional.

In other words, any line having y-intercept is non-proportional.

From the graph attached,

Line has a y-intercept = 20

Therefore, relationship is non-proportional.

Slope of a line passing through two points and ,

m =

Since, the given line is passing through (0, 20) and (60, 28),

Slope of the line 'm' =

m =

   =

y-intercept 'b' = 20

Slope-intercept form of the equation is,

y = mx + b

So the equation will be,

y =
