Answer:- The lines are perpendicular to each other because the graph of y = –6 is a horizontal line with a slope that is undefined, and the graph of x = 1/6 is a vertical line with a slope of 0.
Explanation:-
The x -axis is a horizontal line with the equation y=0. Its slope is 0
The y -axis is a horizontal line with the equation x=0 . Its slope is not defined.
y=-6 is a horizontal line and is parallel to x axis.
∴Its slope is 0. [slope of parallel lines are equal]
x=1/6 is a vertical line parallel to y-axis.
∴ Its slope not defined. [slope of parallel lines are equal]
1) The first thing we need to do is to find the total number of visitors. This is going to be our Sample Space
31+26+2=31+28=59 Visitors altogether
2) The next thing to do is to find the favorable event. Note that we can see that 26 people purchased only one costume.
3) The final and last step is to find the probability, so we can write out the following:
Thus, this is the answer: 0.90
Answer:
y + 1 = -1/2(x - 8)
General Formulas and Concepts:

Slope Formula:
Point-Slope Form: y - y₁ = m(x - x₁)
Step-by-step explanation:
<u>Step 1: Define</u>
f(8) = -1 → Coordinate (8, -1)
f(6) = 0 → Coordinate (6, 0)
<u>Step 2: Find slope </u><em><u>m</u></em>
<u>Step 3: Write Function</u>
<em>Substitute into general form.</em>
