Answer:

y = -7x - 16

Step-by-step explanation:

The formula for the equation of a line is y=mx+b, where m is the slope and b is the y-intercept. Since we already know the slope, all that is left is the value of b, which can be found by substituting the values of the point (-1, -9) into the equation and solving:

-9=-7(-1)+b

-9=7+b

b=-9-7=-16

With this, we get the value -16, making the equation y = -7x - 16
