Answer:

A linear equation cannot be used

Step-by-step explanation:

If it's a linear, then

[tex]\dfrac{y_2-y_1}{x_2-x_1}=constant[/tex]

Substitute the values from the table:

[tex]\dfrac{70-60}{5-1}=\dfrac{10}{4}=2.5\\\\\dfrac{80-70}{20-5}=\dfrac{10}{15}=\dfrac{2}{3}[/tex]

[tex]2.5\neq\dfrac{2}{3}[/tex]
