Remark
Perpendicular slopes are found by using the formula m1*m2 = - 1. That is followed by using the given point to determine the y intercept.
Solution
<em><u>Step One</u></em>
Find the slope of the new line
m1 = - 1/3
m2 = ??
m1 * m2 = - 1
(-1/3) * m2 = - 1
You could continue by changing (-1/3) to a decimal.
(-0.3333333333) * m2 = -1 Now divide by the decimal
m2 = - 1/ (-0.3333333333)
m2 = 3 which is what my calculator tells me the answer is.
<u>Step Two</u>
So far what you have is
y = 3x + b
Use the point (-3, -7) to get the y intercept.
-7 = 3(-3) + b
b - 9 = - 7
b = -7 + 9
b = 2
y = 3x + 2 Answer
Graph
The graph shown below is both lines plotted in desmos. The red line is y = 3x + 2 which is perpendicular to the given graph y = (-1/3)x +5 which is in blue.
The green dot is the point (-3 , - 7)
A U B is the set of elements which are in A, in B, or in both A.
Since,
A = {2, 3, 6}
B = {2, 4, 5, 7}
To find A U B, we have to write all numbers that are in A and/or in B. The number that are in both sets must not be written again.
A U B = {2, 3, 6, 4, 5, 7}
Writing then in acending order:
A U B = {2, 3, 4, 5, 6, 7}
Answer: A U B = {2, 3, 4, 5, 6, 7}.
