Answer:
x = 0
Step-by-step explanation:
We can find slope using this formula:
So we plug it in like this:
We see that the slope is undefined so it will be a straight vertical line
So in order to pass through y = -5 and y = -2, x would have to equal 0.
Therefore, the equation is x = 0

Hello!
Find the coordinate where x = -1:
At x = -1, y = 1, so the coordinate is (-1, 1).
Find the coordinate where x = 2:
At x = 2, y = -2, so the coordinate is (2, -2).
Find the rate of change between the points using the slope formula:
Plug in the coordinates above:
Simplify:
Thus, the rate of change between the points is -1.
Answer:
the number of possible selection is 12650
Option b) 12650 is the correct answer.
Step-by-step explanation:
Given the data in the question;
total number of students n = 25
number of student selected r = 4
= ²⁵C₄
= 25! / ( 4!( 25 - 4 )! )
= 25! / (4!(21)!)
= 12650
Therefore, the number of possible selection is 12650
Option b) 12650 is the correct answer.
