The coordinates below lie on the line with the given slope. find the missing coordinate value. (2,2) (5,y) slope = 2

vodka [1.7K]

Step-by-step explanation:

Hey there!

The given points are; (2,2) and (5,y).

Slope (m) =2

Using formula for slope, we get;

$m = \frac{y2 - y1}{x2 - x1}$

Put all values.

$2 = \frac{y - 2}{5 - 2}$

Simplify it to get value of"y".

$2 = \frac{y - 2}{3}$

$6 = y - 2$

$y = 6 + 2$

Therefore, y= 8.

Hope it helps...

Answer:

(B) 20

Step-by-step explanation:

Let small puppet be represented by-----------------s

Let large puppet be represented by-----------------l

Total number of puppets expression will be: s+l =25---------a

The expression for total costs will be : 1$ s + $2l=$30-------b

Equation a can be written as; s= 25-l ------------c

Use equation c in equation b as

$1( 25-l )+$ 2l = $30

25-l + 2l = 30

25+l =30

l= 30-25 =5

l, large puppets = 5

s, small puppets = 25-5 = 20

Answer choice A is incorrect because 25 is the total number of all puppets

Answer choice C and D are incorrect because the numbers are less that that of small puppets.
