Answer:
Price of skateboard= [tex]3k-5[/tex]
Step-by-step explanation:
Given: The price of a skateboard is 5 dollars less than 3 times the price of a pair of knee pads.
Lets assume the price of the knee pads be "k".
As given, The price of a skateboard is 5 dollars less than 3 times the price of a pair of knee pads.
∴ y-intercept is 5 and slope will be 3.
using y intercept expression to form an expression.
we know, [tex]y= mx+b[/tex]
∴ Price of skateboard= 3\times k-5
Price of skateboard= [tex]3k-5[/tex]
Hence, expression for price of skateboard is [tex]3k-5[/tex]
