4) Here is a graph that represents a proportional relationship. a

General equation of line is:

(a)

Where c represent y intercept then the value of c is zero.

so equation is:

Where m represent the slope.

Pick two point from graph .

So

this equation represent this graph.

(c)

The equation of line is straight line so graph title is straight line.

(d)

At x=30 then the coordinates of graph is:

(b)

Lebel the axes is

That mean value of y is double .

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
