The price of the box of 15 stickers is $6. The price of the box of 25 stickers is $8. All prices are without tax, and the price of the boxes is the same. A Write an equation which tells the price Y for the number of X stickers.

Respuesta :

Answer:

[tex]y=0.2x+3[/tex]

Step-by-step explanation:

Let

x ----> the number of stickers

y ----> the price of the boxes

we have the points

[tex]A(15,6),B(25,8)[/tex]

Find the slope

[tex]m=(8-6)/(25-15)[/tex]

[tex]m=2/10=0.20[/tex]

Find the equation of the line into point slope form

The equation is equal to

[tex]y-y1=m(x-x1)[/tex]

substitute the value of m and the point A

[tex]y-6=0.2(x-15)[/tex]

[tex]y=0.2x-3+6[/tex]

[tex]y=0.2x+3[/tex] ----> linear equation that represent the situation
