Slope equals the change in the vertical (Y value) divided by the change in the horizontal (X value), the slope of a horizontal line is zero and equation of line is Y =12. So option C is correct.
<h3>What is equation of line?</h3>
A straight line's general equation is y = mx + c, where m is the gradient and y = c is the value at which the line intersects the y-axis. This value c is known as the y-axis intercept.
Here,
Since the Y-axis is vertical, a line perpendicular to it would be horizontal.. The slope of a horizontal line is zero, because slope is the change in the vertical (Y value) divided by the change in the horizontal (X value), and the vertical coordinate does not change from the -3 of the point given.
If we start with the slope-intercept form of an equation of a line
Y = mX + b,
we can write Y = 0X + (12)
Y =12
Slope is the vertical change (Y value) divided by the horizontal change (X value); the slope of a horizontal line is zero, and the equation of the line is Y =12.

Step-by-step explanation:
Answer:
The area is changing at 2 m²/d.
Step-by-step explanation:
The area of a rectangle is given by:

Where:
l is the length
w is the width
We have that the length is increasing at a rate:

And the width is decreasing at a rate:
The change in the rectangle's area is the following:
When the length is 8 meters and the width is 18 meters we have:
Therefore, the area is changing at 2 m² per day.
I hope it helps you!

Answer:
12P3 = 1320
Step-by-step explanation:
How you need select three persons of a group of twelve persons, but in the selection each member of the group has a different position, then you need use a permutation
Permutation is defined how

In our case n = 12 and r = 3
Thus

12P3 = 1320
