This is slope intercept form equation question.

Mathematics
1 answer:
netineya [11]3 years ago
3 0

Answer:

The answer to your question is y = x

Step-by-step explanation:

Data

A (1 , 1)

B (2, 2)

Process

1.- Find the slope (m) of the line

   m = (y2 - y1) / (x2 - x1)

x1 = 1     y1 = 1

x2 = 2   y2 = 2

- Substitution

   m = (2 - 1) / (2 - 1)

   m = 1 / 1

- Result

    m = 1

2.- Find the equation of the line

    y - y1 = m(x - x1)

- Substitution

    y - 1 = 1(x - 1)

- Simplification

   y - 1 = x - 1

   y = x - 1 + 1

- Result

   y = x

SOMEONE PLEASE HELP ME!!!!!!
VashaNatasha [74]

Answer:

There are multiple possibilities. One is there are 12 boys, and 16 girls. 12+16= 28 which is between 20 and 30. That would be 12:16, which can be simplified to 3:4. There is also 9 boys, and 12 girls. that would be 9:12, which can be simplified to 3:4. Also, 9 + 12 = 21, which is between 20 and 30.

Use the Pythagorean Theorem to find the measure of the space diagonal line in the box
madreJ [45]

Answer:

14.42inches

Step-by-step explanation:

Given the following

b = 5 in

c = 8in

we are to find the measure of the space diagonal line

Using the pythagoras theoreml

l^2 = b^2 + c^2

l^2 = 13^2 - 5^2

l^2 = 169 -25

l^2 = 144

l = 12in

To get the measure of the space diagonal line in the box, we will use the pythagoras theorem;

s^2 = l^2 + c^2

s^2 = 144 + 8^2

s^2 = 144 + 64

s^2 = 208

s= 14.42inches

Hence the required length ix 14.42inches
