Answer:

y = -8x

Step-by-step explanation:

First let's look at what slope-intercept form is.

y = mx + b

m is the slope, which in this case is -8.

b is the y-intercept, which we will find later.

Now that we have identified the parts of the equation, let's plug in what we know. Use the point given for your x and y values.

y = mx + b

16 = -8(-2) + b

Let's simplify this to find b.

[multiply] 16 = 16 + b

[subtract 16] 0 = b

We now have our b-value, which is also our y-intercept. Plug in this value into the standard slope-intercept equation.

y = -8x

This is your equation.

Check this by plugging in the point again.

16 = -8(-2)

[multiply] 16 = 16

This expression is true; therefore, your answer is correct.

Hope this helps!
the answer would be
y = -8x
