Question

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

Answer 1

Answer:

The value of $a$ is 6.

Step-by-step 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:

$y = \frac{a}{3}\cdot x +2$ (1)

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

$-4 = \frac{a}{3} \cdot (-3)+2$

$-4 = -a + 2$

$a = 6$

The value of $a$ is 6.
