Which unit rate corresponds to the proportional relationship shown in the graph? drag and drop the answer into the box to match the graph with its unit rate. a graph with a line running through coordinates left parenthesis 0 comma 0 right parenthesis and coordinates left parenthesis 6 comma 9 right parenthesis. 0.33 cm/s0.5 cm/s0.67 cm/s1.5 cm/s

1.5 cm/s

Step-by-step explanation:

The unit rate is the same as the slope.

To find the slope, we use the slope formula:

Using our points, we have

m = (9-0)/(6-0) = 9/6 = 3/2 = 1.5 cm/s

Equation of line having coordinates

Now,as given the line passes through (0,0) and (6,9).

So, equation of line passing through (0,0) and (6,9) is :

→

As , slope intercept form of line is , y = m x +c

By comparing two lines

we get, m = 1.5

We can also find directly  slope of line using the formula

m= cm/s→→option (D)
