The equation for a line is y=mx+b
m is the slope, so when a line is perpendicular to another line is has a slope which is an opposite reciprocal, so change the -1/2 (the slope of the other line) to 2/1 or just 2
so m=2
now you need to plug in the point they give you for x and y
y=mx+b
4=2(4) + b
simplify
4=8 + b
subtract 8 over
-4 = b
now that you know that slope (m) and the y-intercept (b) you can plug those two numbers into the original equation for the answer
y= 2x -4
Answer:
1 foot?
Step-by-step explanation:
You subtract 13 from 12 to get the base divider.
The probability that the student selected is 5/8.
According to the question,
We have the following information:
A class consists of 30 women and 18 men.
Now, total students in the class = Number of women + number of men
Total students = 30+18
Total students = 48
Now, the probability that the student is a woman:
Probability of an event = Number of women/total number of students
30/48
(More to know: probability of an event can not be greater than 1.)
Now, converting this into the simplest form by dividing both the numerator and denominator by 6:
5/8
Hence, the probability that the student selected is 5/8.

Answer:
12A-12B
Step-by-step explanation:
In the parentheses, it is A-B. Using the distributive property you break up the parentheses then you have 12xA - 12xB. This is known as the "Santa Hat". The lines mean that you do each function to each constant, variable, or term.
