Question

A bottle of power drink costs $2.25. Which graph represents the relationship between the number of bottles and the total cost?

Answer 1

$Let \: number \: of \: power \: drink \: bottles =x$

$Cost \: of \: each \: bottle = \ 2.25$

$Total \: cost \: of \: bottles = y$

$Linear \: Equation : y = 2.25 \times x$

$\begin {tabular} {|c|c|c|} </p><p>\cline {1-3} x&2&4 \\</p><p>\cline {1-3} y=2.25x&4.5&9 \\</p><p>\cline {1-3} (x,y) &(2,2.25)&(4,9) \\</p><p>\cline {1-3}</p><p>\end {tabular}$

$Plotting \:the \:points \: on \: a \:graph \\we \: get \:a \: linear \: equation \: attached \:above .$
