(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.

DaniilM [7]

Answer:

Step-by-step explanation:

b(a + 1) + a = b*a + b + a = ab + b + a

1) b(2a +1 ) = b*2a + b*1 = 2ab + b  Not equivalent.

2)a + (a +1)*b = a + ab+ b     Equivalent

3) (a +1)(b+ a) = a*(b +a) + 1*(b+a) = ab+ a² +b + a  Not equivalent.

4) (a + 1)b + a = ab+ b + a   Equivalent

5) a + b(a+1) = a +ab + b Equivalent

6) a + (a +1) + b = a + a + 1 + b = 2a + 1 +b  Not equivalent.

7) a(b +1) + b = ab + a + b  Equivalent
