The equation that represents Joan's function is [tex]y =\frac 17x + 1[/tex]
Linear function
A linear function is a function whose value changes at a constant rate.
A linear function is represented as:
[tex]y = mx + c[/tex]
Where
- m represents the rate
- c represents the initial value i.e. the distance
From the question, we have:
- [tex]m_1 = \frac 17[/tex] -- Joan's rate
- [tex]m_2 = \frac{3}{30}[/tex] -- Ginny's rate
The distance covered by Ginny in 10 minutes is:
[tex]d = \frac{3}{30} \times 10[/tex]
[tex]d = 1[/tex]
This represents the initial value of Joan's function
Hence, the equation that represents Joan's function is [tex]y =\frac 17x + 1[/tex]
