What is the y-intercept of the line -7x-5y=-45?

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.

-9

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

Step 1: Add 7x to both sides.

Step 2: Regroup terms.

Step 3: Divide both sides by -5.

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!

A brainliest will be greatly appreciated!

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
