Answer:

2/3x - y = -13/3

Step-by-step explanation:

Step 1: Find slope <em>m</em>

m = (3 - 5)/(-2 - 1)

m = -2/-3

m = 2/3

y = 2/3x + b

Step 2: Find <em>b</em>

5 = 2/3(1) + b

5 = 2/3 + b

b = 13/3

Step 3: Write equation in slope-intercept form

y = 2/3x + 13/3

Step 4: Move 2/3x over

-2/3x + y = 13/3

Step 5: Factor out -1

-1(2/3x - y) = 13/3

Step 6: Divide both sides by -1

2/3x - y = -13/3

Use a inequality symbol to compare -3x+7 -10-2

Hey there,

Let's remember that a (inequality symbol) is things like (<), (>), (≤),(≥), (≠).

So, I believe that (-3x+7) and (-10-2) are separate. So we will find that out :)

Let's first do (-3x+7). As simplifying this expression here, we take that "x" of for a while and just stick to (-3+7). 

    -3
+   7
______
     4

Let's bring that "x" back, and the answer would be 4x for a while.

So far, 4x is the answer.
_____________________________________________________________

Now, Let's work on the other side.

We are talking about (<span>-10-2)

    -10
-      2
_______
</span>     -12

So, by solving the answer to (-10-2), we got -12.

So, let's determine what is greater . . . . . 

What \ is \ greater?

-12 or 4.

-12 is on the negative side, and the number 4 is positive. This would conclude that 4 is great than -12.

Your correct answer would look like . . . 

<span>(-3x+7) > (-10-2)
</span>
I really hope this helps you alot.

Answer:  The steps and answers to the first two are below but you need to understand slope  = change in y / change in x  = y2 - y1/ x2 - x1  

And you need to understand  y = mx + c  

m= slope   c is y intercept

Substitute either point given  - only use one as the x and y  and find c

Step-by-step explanation:

1.      You need to follow the steps -

          the point is given as  (2,5)  = (x,y)  

So what this means is  x =2 and y =5

Simple substitutions is the step  5   = 3 x 2 + c

                                                     5 = 6 + c  or easier to see is  c + 6 =5

subtract 6 from both sides   c +  6   =  5

                                                    -6      -6

                                           __________________

                                              c           =  -1

2.

 x1,y1           x2,y2

( 3,2)   and (5,6) are two points on the line  

you already calculate the slope which is   m = noy2-y1/x2-x1 = 6-2/5-3 = 4/2 = 2

Remember y= mx + c

                   y = 2 x + c

now substitute in (3,2) which is (x1, y1) into the x and y in your equation

                  2  = 2 (3)  + c

                  2 = 6 + c

 subtract 6 from both sides

                  -4 = c

Now you should use this and do your last question  yourself

Lexi asked 325 students which fruit they preferred, bananas or pineapples. 200 students said they preferred pineapples. What per
Serjik [45]

Answer:

38.46%

Step-by-step explanation:

Given,

The total number of students = 325

The number of students preferred pineapples = 200

Therefore, The number of students preferred bananas = (325 - 200) = 125

Among 325 students, banana is preferred 125 students

Among 1 student, banana is preferred 125/325 students

Among 100 students, banana is preferred (125*100)/325 students

= 500/13

= 38.46% (2 decimal places)
