Question

What would be the equation for this line? 80 60 40 20 time in minutes 2 3 4 5 6 7 8 9 X distance in miles

Answer 1

the equation of the line is given as follows,

first we take points on this line

A(2,20)

and

B (4,40)

so, the equation of the line is,

`y-20=(40-20)/(4-2)(x-2)`
`\begin{gathered} y-20=(20)/(2)(x-2) \\ y-20=10x-20 \\ y=10x \end{gathered}`

thus, the equation of the line is

y = 10x
