I think you have to figure out the gradient, so you take the 2 points and put it into the equation
change in y divided by change in x aka
y2-y1/x2-x1
so for question 3:
y2=4 and y1=3
(taken from the first and second coordinates)
x2=3 and y1=7
put these values jnto the equation
4-3/3-7 = 1/-4 (can be written as negative 1/4)
for question 4 its the same thing:
y2=9 and y1=5
x2=4 and x1=2
put into equation
9-5/4-2 = 4/2
hope this helps, im also hoping your teacher already has taught this because i didnt go into detail of where the equation came from, if not ask me and ill gladly help X
Answer:
∠MNP is your answer
Step-by-step explanation:
Note the angle and the order it is said. It is ∠ABC, which means the double line side, one curve line angle, and then triple line side.
Now look at the second triangle, the same double line side (NM), one curve line angle (∠N), and triple line side (NP)
Put them together: ∠MNP is your answer

Using the rational root theorem, it is found that your friend is correct.
<h3>What is the rational root theorem?</h3>
- It is a theorem that states that for a polynomial with integer coefficients, with q being the factors of the leading coefficient and p being the factors of the constant, every <u>possible rational root</u> is the format .
In this problem:
- The leading coefficient is 1, hence it's only factor is , thus guaranteeing that every possible rational zero is an integer, which means that your friend is correct.

Answer:
-15.
Step-by-step explanation:
Arithmetic sequence:-
t2 = a + d
= -19 + 4
= -15.
The rate of change is 4 so your answer would be D. 4
