Answer:

y = -3x

Step-by-step explanation:

formula of slope is y=mx+b

you substitute the equation and you'll get

y = -3x

Answer:

y = -3x + 0

OR (choose one of them)

y = -3x

Step-by-step explanation:

slope intercept form: y = mx + b

slope M = -3

y-intercept B = 0

y = -3x + 0

y = -3x

(When you don't put nothing after the slope the eqaution understands that the y-intercept is at the middle which is zero, so if there is nothing after the slope there is an invisible 0. So there is an invisible ( + 0) you can choose to add the + 0 or not, either way it's correct the only place where it's mandatory is if the y-intercept is NOT 0, then you write it out because the person can't guess what the y-intercept is lol.)

What is the difference of the fractions? Use the number line to help find the answer

alisha [4.7K]

Answer:

-7/10

Explanation:

Given the expression

$\frac{1}{2}-1\frac{1}{5}$

We can rewrite the expression as:

$\frac{1}{2}-\frac{6}{5}=\frac{5}{10}-\frac{12}{10}$

The number line showing the location of the two numbers is attached below. Therefore:

$\frac{5}{10}-\frac{12}{10}=-\frac{7}{10}$

Which best describes the relationship between the line that passes through the points (6, –1) and (11, 2) and the line that pass

saw5 [17]

Answer:

Step-by-step explanation:

slope of line through (6,-1) and (11,2) = (-1 - 2)/(6 - 11) = 3/5

slope of line through (5,-7) and (8,-2) = (-7 - (-2))/(8 - 5) = -5/3

product of the slopes = -1, so the lines are perpendicular.

create a dot plot for this data how many books did you read this summer 5 5 9 2 4 5 8 7 5 2 4 9 8 5 9 2

Shtirlitz [24]

A dot plot is a type of frequency graph just like a histogram. Whereas a histogram uses 2 axes and bars to fill the frequency graph, the dot plot is only a number line with dots. A number line presents a parameter. For this problem, this is the number of books. When you ask a group of people on how many books they've read this summer, they would give a variety of numbers. These numbers are data point as listed above. If you want to see the frequency, you place a dot on top of the number every time a person answers that number. For example, 3 people said they've read 2 books this summer. So, on top of number two, you place 3 dots. Overall, you will be able to see which has the highest frequency by stacking the dots on top of each other.

The dot plot for this data set is shown in the picture.
