the first one is true
this is the equation: y=ax
you can put one of the points on the line as x and y. for example (2,8)
[tex]8= a \times 2 \\ 8 = 2a \\ a = \frac{8}{2} = 4[/tex]

Answer:

4

Step-by-step explanation:

Find the rate of change [slope]:

[0, 0] and [2, 8]

OR

[1, 4] and [0, 0]

-y₁ + y₂\-x₁ + x₂ = m

[tex]\frac{-8 + 0}{-2 + 0} = \frac{-8}{-2} = 4 \\ \\ OR \\ \\ \frac{0 - 4}{0 - 1} = \frac{-4}{ -1} = 4[/tex]

I am joyous to assist you anytime.
