Answer:

The answer is

[tex] \huge y = - 3x + 5[/tex]

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

From the question we have

[tex]y + 4 = - 3(x - 3) \\ y + 4 = - 3x + 9 \\ y = - 3x + 9 - 4[/tex]

We have the final answer as

[tex]y = - 3x + 5[/tex]

Hope this helps you
