Question

Fill in the missing numbers to the linear eqution

Answer 1

`y=-30x+0`

Explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
`k=(y)/(x)` or
`y=kx`

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem the linear equation represent a proportional relationship, because pass through the origin (0,0).

Find the value of the constant of proportionality k

For x=1, y=-30

substitute

`k=(-30)/(1)=-30`

so

the linear equation is

`y=-30x`

therefore

`y=-30x+0`
