Question

Help :(( if the point (-3,-4) lies on a graph of the equation 3y=ax+6, then value of a

Answer 1

The value of
`a` is 6.

Explanation:

Let the line be represented by
`3\cdot y = a\cdot x + 6`, where
`x`,
`y` are the independent and dependent variable, respectively. The explicit form of the formula is:

`y = (a)/(3)\cdot x +2` (1)

To know the value of
`a`, ,we need the values of
`x` and
`y` and solve the resulting expression:
`(x,y) = (-3,-4)`

`-4 = (a)/(3) \cdot (-3)+2`

`-4 = -a + 2`

`a = 6`

The value of
`a` is 6.
