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....

so in this case -3 would be the
because it's the y in the ordered pair and it's the second one. Then one of the 5's would be
and 9 would be
and then the other 5 would be
.
now if we plug it in

now we can tell that we can't divide by zero so the slope would be unidentified and that's it.
X=7
Step 1: add nine to both sides it becomes
-2x=-23+9 —> -2x=-14
Step 2: divide by -2 on both sides it becomes
X=-14/-2 —> x=7
