4y-y is NOT equivalent to 4.
4 is multiplied by 'y', and then 'y' is subtracted from that equation. Even if y=1, your equation would look like 4x1-1=3.


Hope that made sense:)

(5,9), (5-3)<br> what is the slope?
monitta

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

When you want to find out what the slope is, you have to remember what the formula is first....

m=\frac{y}{x} =\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

so in this case -3 would be the y_{2} because it's the y in the ordered pair and it's the second one. Then one of the 5's would be x_{2} and 9 would be y_{1} and then the other 5 would be x_{1}.

now if we plug it in

\frac{-3-9}{5-5} =\frac{-12}{0}

now we can tell that we can't divide by zero so the slope would be unidentified and that's it.
