How much does one slice of pizza cost? Is the graph a proportional relationship?

What’s the equation for this graph?

Explanation:

(a)

take best two coordinates: (2,9),(3,13.5)

One slice of pizza costs $4.5

(b) Yes the graph shows proportional relationship as its a straight linear line

(c) using the formula: y = mx + b ....where m is slope and b is y-intercept.

Here the y-intercept is 0 and we found slope that is 4.5.

Therefore:

y = 4.5x + 0

y = 4.5x

step-by-step explanation:

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.
