Answer:
I think your answer 4 I'm not sure tho hope this helps
Step-by-step explanation:
set o= o
set t= t
those are the set of letters used to form the set
Formula for slope: 
y₂: 6
y₁: 8
x₂: 1
x₁: -2
Plug them into the slope equation:

--> 
---> 
The slope is
.
We keep the 2x^2 because we can only subtract something from that if it also is squared. From there, we subtract the 7x from 2x^2-11. Since there is no previous x's in the 2x^2-11, we just make it -7x. So, without even continuing the problem, we see that A) is the correct answer because it is the only one with -7x.
Answer:
This equation has one solution
Step-by-step explanation:
Number of solution depends on the involved variables so here in this equation only one variable involve so one solution exist.
