Answer:
1. Yes, the lines are perpendicular.
2. 
Step-by-step explanation:
The first equation of Exercise 1 is incomplete. Let's assume that it is:
Where "n" is a number.
First, it is important to remember that the equation of a line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
By definition, the slopes of perpendicular lines are negative reciprocals.
1 . If you solve for "y" from the first equation, you get:
You can identify that the slope is:
The second equation of the line is:
And its slope is:
Since the slopes are negative reciprocals, the lines are perpendicular.
2. Given the first equation of the line:
You can identify that:
Since the first line and the second one are perpendicular, you know that the slope of the other line is:
According to the information given in the exercise, both lines have the same y-intercept; therefore, the equation of the second line is:
Answer:
the gradients are the most important features.
Step-by-step explanation:
if the linear functions are parallel with different constants, they won't intercept. If they are parallel with an equal constant, they are the same function. Any linear functions with different gradients will always intercept
Answer:
1/3
Step-by-step explanation:
6/18 = 1/3
Ok so you are correct that x is input and y is output
the
you could be talking about a function in general or a kind of function normally used called a one-to-one function which I will assume you are talikning about
one-to-one funciton has that for every input, there is only 1 output, ie, x never repeats with a diffent y
example
(1,2), (2,2) is a function since x didn't repeat
(1,2), (1,3) is not since x repeats with a different y
points given are
(-5,1),(-3,-2), (3,0),(1,1),(2,0),(6,4)(8,-2),(8,7)
we see that the points (8,-2) and (8,7) make it not a function since it is the same input (8) that gives 2 different outputs
professor octavious is wrong since 8 repeats
