Answer:
It allows to to know y-intercept formula which is used to graph a line.
Step-by-step explanation:
Y-intercept formula:
y=mx+b
M: slope (keep in fraction if it is fraction, to help you graph)
B: y-interecept
Answer:
Slope= 4
Step-by-step explanation:
y2-y1/x2-x1
5=x1 8=y1 etc.
12-8/6-5
=4/1
Answer:
z-test.
Step-by-step explanation:
We want to perform an hypothesis test for a population mean.
In the case that the <u>standard deviation of the population is known</u> and the population distribution is normal, even if the sample is small, <u>we will use a z-test</u>.
The usual case is to not know the standard deviation of the population, in which case a t-test is adequate instead of a z-test, taking into account the degrees of freedom of the sample.
Answer:
See explaination
Step-by-step explanation:
While graphing inequalities, think of the inequality sign as an equal sign.
So, y=mx+b.
Say the inequality was y>3x+7, I would think fo the > as an equal sign.
So, in your head, "write" it like this: y=3x+7. Hope this helps.
