Answer:

y = -x - 2

Step-by-step explanation:

You can start with the equation of a line in the slope-intercept form.

y = mx + b

m = slope

b = y-intercept

Look at the graph to find the y-intercept. At what point on the y-axis does the graph intersect the y-axis? Answer: -2. The y-intercept is -2. The value of b is -2.

Now we hjave

y = mx + (2)

or simply

y = mx - 2

Now we need to find the slope.

The slope is the ratio of the rise (difference in y) over the run (difference in x).

Look at the point (6, -7) that is shown in your graph. Go up 1 unit vertically. That is a rise of 1. Now go left 1 unit horizontally. That is a run of -1.

slope = m = rise/run = 1/(-1) = 1

The slope is 1. Now we replace m with -1.

y = mx - 2

y = -1x - 2

y = x - 2

Answer: y = -x - 2

Answer: The equation of this graph can be written in slope intercept form which is what I am assuming you want.  If you do not want that form you can convert to any other form that you so desire.  The slope intercept equation for this graph would be y = -1x - 2.  The -1 is the slope of the line and the -2 is the y intercept.

Maxine types 294 words in 7 minutes. How many words does Maxine type in 11 minutes?<br> 352 words
WINSTONCH [101]

Answer:

462 words

Step-by-step explanation:

Maxine types :

294 words ⇒ 7 minutes

Let the known number of words be x.

So,

294 words ⇒ 7 minutes

x words ⇒ 11 minutes

Therefore,

294 ⇒   7

x      ⇒   11

Now use cross multiplication and find the value of x.

7x = 294 × 11

7x = 3234

Now divide both sides by 7.

x = 462 words.

Hope this helps you :-)

Let me know if you have any other questions :-)

The teacher separated her class of twenty -eight students into two groups. One group has 4 more than twice as many students as t
stiv31 [10]
The class has 28 student. One group has four more students so surat 4 from 28. 28-4=24 since one of the groups have twice as many students as the other divide 24 by 3. 24 / 3 = 8. It says 1 group has for more than twice the other group so that would mean 2/3 of 24 and 4 would be the answer 16+4=20. The first group had 8 students, the other group has 20 students.
