Question

the graph shows the relationship between the number of yogurt drinks and the total number of calories PART Awrite an equation to represent the calories for x drinks y=_________xPART Bwhat is the slope of the graph slope=____________ in a fraction

Answer 1

y=kx

Where k is a constant of proportionality.

Replace x,y by a point from the graph, for example (1,250), and solve for k.

250 =k 1

250= k

Equation:

y=250x

Slope:

slope-intercept form equation:

y=mx+b

Where :

m=slope

b= y-intercept

Since b=o, m= 250

Slope =250
