Type the correct answer in each box. If necessary, use / for the fraction bar(s). John recorded the number of cars passing a traffic signal at intervals of 2 minutes. He plotted his data on this graph.

Slope of the line is =

y-intercept = 5

Step-by-step explanation:

Slope (m) is can be calculated using the formula,

Use the coordinates of any two points located on the line. Let's use, (14, 40) and (10, 30).

Let,

Plug the above values into the formula to find the slope (m).

Slope of the line is =

Find y-intercept using y = mx + b

Where m = slope, and b = y-intercept

Use (10, 30) as (x, y).

30 = 5/2*10 + b

30 = 25 + b

30 - 25 = b

5 = b

b = 5

i think thats the answer i checked it on google
