Answer:

The y-intercept is at the point (0, 9).

Step-by-step explanation:

WE have the y intercept when x = 0:

-7(0) - 5y = -45

-5y = -45

y = -45/-5 = 9.

Answer:

-9

First, we must convert the equation into slope intercept form, by solving for y.

Step 1: Add 7x to both sides.

[tex]-7x-5y+7x=-45+7x-5y=-45+7x\\[/tex]

Step 2: Regroup terms.

[tex]-5y=7x-45[/tex]

Step 3: Divide both sides by -5.

[tex]y=-\frac{7x-45}{5}[/tex]

[tex]y=-\frac{7}{5}x-9[/tex]

Now we can determine the y-intercept by just looking at the equation! the y-intercept is the only constant, -9

I hope this helps!
