What is the slope of a line that is perpendicular to the line y = 1?
O-1
ОО
O 1
O undefined
Answers
Answer: D) Undefined
Explanation:
The equation y = 1 is the same as y = 0x+1
Match that to the form y = mx+b to see that the slope is m = 0
Any horizontal line has a slope of 0.
Notice that we cannot apply the negative reciprocal to this because 0 = 0/1 leads to 1/0 which is undefined
The slope of any vertical line is undefined because we have run = 0 and slope = rise/run = 1/0. The rise can be any number you want (it doesn't have to be 1) and we get the same result.
The slope of a line that is perpendicular to the line y = 1 is undefined.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The equation y = 1 is the same as y = 0x+1
Match that to the form y = mx+b to see that the slope is m = 0
Any horizontal line has a slope of 0.
y = 1 is an vertical line.
The slope of any vertical line is undefined because we have run = 0 and slope = rise/run = 1/0.
= Undefined
Hence, the slope of a line that is perpendicular to the line y = 1 is undefined.

what does the expression 3(20+15) represent?
Answers
Answer:
It represents 3x20 +3x15
Step-by-step explanation:
The expression 3(20+15) represents 20+15 then multiplying it by three.
If you were to solve the expression, the answer would be 105.
20 + 15 = 35
35 x 3 OR 35(3) OR 35 ∙ 3 = 105

Answers
Answer:
[tex]\huge\boxed{\sf Right.}[/tex]
Step-by-step explanation:
[tex](-a+b)^2[/tex]
Let's apply the formula (x+y)² = x² + 2xy + y²
Here, x = -a and y = b
So,
= (-a)² + 2(-a)(b) + (b)²
= a² - 2ab + b²
Hence, it has been proved that (-a + b)² = a² - 2ab + b².

Step-by-step explanation:
You are given the coordinates of each line.
To check if they are parallel or perpendicular, need to find slope.
In this case we can use :
m = (y2 - y1) / (x2 - x1)
So for line a:
(1,5) and (-2, -4)
slope = (-4 - 5) / (-2 - 1)
slope = -9/-3
slope = 3
Line b:
(3, 2) and (1, -4)
slope = (-4 - 2)/(1 - 3)
slope = -6/-2
slope = 3
Line C:
(6, 1) and (-4, 2)
slope = ( 2 - 1) / ( -4 -6)
Slope = 1/ -10
slope = - 1/10
Line A and B are parallel because their slopes are the same.
To check if they are perpendicular, we need to know if their slopes are reciprocals.
Here none of them are perpendicular to each other
