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:
Step-by-step explanation:
Given function:
This is a quadratic function with <u>positive</u> leading coefficient.
It means the graph of the function opens up and therefore it has minimum value of the function at the vertex.
<u>Correct</u> answer <u>choice</u> is A
The answer is 40, just multiply 10 x 4 and you get 40, and just check if it can be divided by 8. and yes so it's 40
Answer: 5 percent
