The four points shown on the graph are ordered pairs 0, 0 and 1, 3 and 2, 6 and 3, 9. These points are joined by a line. The label on the x-axis is Bags of caramel corn. The title on the y-axis is Total cost in dollars. What is the constant of proportionality? Answers are: 3 , one-third , 2 , or one-half

Respuesta :

You would set the problem into slope-interslope form : y = mx + b.
Slope (m) = rate of change           b = y-intercept
Therefore, your in the above:
m =  3
b = 0
The constant proportionality (slope) is 3 and the y-intercept is 0.

you would set the problem up and the answer will be 3 if you need me to explain it more comment down below
