Answer 1

4

Explanation:

Find the rate of change [slope]:

[0, 0] and [2, 8]

OR

[1, 4] and [0, 0]

-y₁ + y₂\-x₁ + x₂ = m

`(-8 + 0)/(-2 + 0) = (-8)/(-2) = 4 \\ \\ OR \\ \\ (0 - 4)/(0 - 1) = (-4)/( -1) = 4`

I am joyous to assist you anytime.

Answer 2

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)

`8= a * 2 \\ 8 = 2a \\ a = (8)/(2) = 4`
