The graph below shows the prices of different numbers of sunglasses at a store: which equation can be used to determine p, the cost of s sunglasses? haha..

we can see that

curve is a straight line

y-axis is price(p)

x-axis is number of glasses (x)

so, firstly we will find slope

we can select any two points

(0,0) and (2,9)

x1=0, y1=0 , x2=2 , y2=9

now, we can plug values

now, we can use point slope form of equation

so, we can plug it

now, y is p

so, we get our equation as
