Question

Here is the graph and equation for Turtle F from 3-1.1

Which equations could describe the graph?

Answer 1

All but the last

Explanation:

Every 4 cm takes one second so y = ¹/₄x

and
`\frac14=(1\cdot5)/(4\cdot5)=\frac5{20}` so y = ⁵/₂₀x also apply

and:

`y\ =\ \frac14x\\^(/\, x)\quad\ ^(/\, x)\\\frac yx = \frac14`

so the third also apply
