The answer is probably 2 because if you plug in the numbers you would get 
3x-4=-12 divided by -6 = +2.

What is the slope of the line shown?
koban [17]

Answer:

So buddy this is going to get a bad rating I know but I'm going to help you out as much as I can without seeing a picture so for linear equations the formula is y=mx+b anyways the slope is m and to find it, look at the line and see how many times it goes up till it lands on a correct point. once you have that you can see how many times it went up and over. Because your slope is your rise over run (rise/run) and so for example <em>if</em> it was c then it would be 3/3 meaning it goes up 3 and over 3. So to find the right one just find a starting point and see how much it goes over to the right. if it goes over to the left then its negative instead of run over to the right. And if it goes down instead of rise then its negative. Hope this helps you find your answer now and in the future.

I need help now please, I can’t figure this out
otez555 [7]

Answer:

B. 1,4

Step-by-step explanation:

1. substitute 4x for y in the second equation since we know y=4x(to find x)

6x-4(4x)=-10

2.solve for x

6x-4(4x)=-10

-4•4x=-16x

6x-16x=-10

6x-16x=-10x

-10x=-10

-10x/-10=-10/-10

x=1

3.substitute 1 for x in either equation(since x=1)to find y

y=4(1)

y=4

x,y=1,4

hope this helps!
