The graph shows the number of pictures a traffic camera takes each minute. What does the point (8, 4) on the graph represent?
Every 4 minutes, 8 pictures are taken.
Every 8 minutes, 4 pictures are taken.
Eight pictures are taken between the third and fourth minute.
Four pictures are taken between the sixth and eighth minute.

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3
