Answer:
Step-by-step explanation:
There are 20 groups of fish
The general equation for a linear equation is 
- y is the y-coordinate
- x is the x-coordinate
- m is the gradient of the slope
- c is where is passes through the y axis
So if you breakdown this equation (
) you are able to see that 2/3 is in the same spot as 'm' which is the gradient or slope of the line.
Also if there was a negative infront of 'm' then the gradient would slope down '\' instead of up '/'
Answer:
The null hypothesis would say that class size has no effect on students learning.
Step-by-step explanation:
Null hypothesis is a type of hypothesis that is used in statistics which proposes that there is no difference between a certain characteristic of a population or the data - generating process.
Now, in this question,the school district is considering increasing class size in the elementary schools but we want to check whether larger classes may have a negative effect on students learning.
Thus, the null hypothesis would reject this claim of larger classes having negative effect on students and say that class size has no effect on students learning.
Answer:Yes.
Step-by-step explanation: Substitute either of the those values and you should get the other.
For instance, substituting x = 1 got you y = 5. If you had substituted x = 1 and got a different y-value, then the coordinates would have been incorrect.
