Find the equation of the line passing through the points 7,2 and 9,1
bija089 [108]

9514 1404 393

Answer:

  y = -1/2x +11/2

Step-by-step explanation:

The slope of the line is ...

  m = (y2 -y1)/(x2 -x1)

  m = (1 -2)/(9 -7) = -1/2

The y-intercept is ...

  b = y -mx

  b = 2 -(-1/2)(7) = 11/2

Then the slope-intercept equation is ...

  y = -1/2x +11/2

_____

<em>Alternative solution</em>

A general form equation for the line can be ...

  (y1 -y2)(x -x1) -(x1 -x2)(y -y1) = 0

  (2 -1)(x -7) -(7 -9)(y -2) = 0

  x-7 +2y -4 = 0

  x +2y -11 = 0 . . . . . general form equation

  x +2y = 11 . . . . . . . standard form equation

Note that we want the x-coefficient to be positive, so we chose the order of the points to make that be the case.

Emilio cay type 850 words in 17 minutes. How many words can he type in one hour?
Nutka1998 [239]

Answer:

3,000 words

Step-by-step explanation:

we know that

Emilio cay type 850 words in 17 minutes

Remember that

1\ h=60\ min

so

using proportion

Find out how many words can Emilio type in 60 minutes (one hour)

Let

x ---> the number of words

\frac{850}{17}\ \frac{words}{minutes} =\frac{x}{60}\ \frac{words}{minutes}\\\\x=60(850)/17\\\\x= 3,000\ words
