Find the constant of proportionality of the table and express it in an equation

The constant of proportionality is 2.5. This can be expressed as (cups of sugar) * 2.5 = cups of flour

Step-by-step explanation:

The constant of proportionality is y/x. Since flour comes second, we'll plug flour in for y here.

5/2 = 2.5

15/6 = 2.5

20/8 = 2.5

The constant of proportionality is 2.5. This can be expressed as (cups of sugar) * 2.5 = cups of flour

Step-by-step explanation:

Pick two points on the line

(0,-5)  and (1,-1)

We can find the slope using

m = (y2-y1)/(x2-x1)

   = ( -1 - -5)/(1 - 0)

  (-1+5)/(1-0)

    4/1

  = 4
