The answer is a, -8. first you have to set up the equation -3x=24 split it down the middle, then you have to get rid of the x on one side, so you have to do the opposite, right now it’s saying -3*x, opposite of multiplication is division. so you take -3/-3 and you’re left with x, then you have to do the same to the other side, 24/-3 and you get -8. so x=-8

The answer is B. 0.25.

How do I graph y+x= -3

Nitella [24]

Answer:

Use Desmos.com/calculator

Step-by-step explanation:

Remember, y=mx+b

y is equal to any given y point

x is equal to any given x point

m is equal to slope

b is equal to the y-intercept, or where x = 0 and the line crosses the horizon line.

In order to graph the line correctly, you have to isolate y.

y+x=-3

y=-x-3 would be equal to y=mx+b format

slope is negative 1

y intercept is negative 3

start on the y line, go to (0,-3) and start your line.

slope is negative 1, so you go down one and right one.
