Answer:

18 sections

Step-by-step explanation:

To answer this problem, you need to do 6 divided by 1/3. When dividing with fractions, do KFC; keep, flip, change. 6 is the same thing as 6/1 and you would KEEP that like it is. Then, you will FLIP 1/3 to 3/1. Next, you CHANGE the division sign to multiplication. This leaves you with 6/1 times 3/1. Multiply your numerators, then your denominators. 6 times 3 is 18 and 1 times 1 is 1. You are left with 18/1, or 18 as you final answer.

Write an equation of the line that passes through the points (-2, -3) and (1, -3)._____________ What is the slope?___

Gre4nikov [31]

Answer:

y = -3, slope = 0

Step-by-step explanation:

1) First, find the slope of the line. Substitute the x and y values of the given points into the slope formula, $m = \frac{y_2-y_1}{x_2-x_1}$ , and solve:

$m = \frac{(-3)-(-3)}{(1)-(-2)} \\m = \frac{-3+3}{1+3} \\m = \frac{0}{4} \\m = 0$

Thus, the slope is 0.

2) If a line has a slope of 0, that means it is horizontal. All horizontal lines are represented by the equation y = a number. That number is determined by the y-value of all the points the line intersects. Thus, find the y-value of the given points and put it into the equation. Looking at the given points, that number would be -3, so y = -3 is the equation.
