Match the word to the definition.
1. decomposition the act of separating into basic elements
2. heliograph a device used for transmitting messages by reflecting sunlight
3. vivid an instrument for measuring force or energy
4. dynamometer full of life **Weegy:** A device used for transmitting messages by reflecting sunlight is a heliograph. (More)

where b is the constant. (-1, 0) m = -2

y = mx + b

0 = (-2)(–1) + b

0 = 2 + b

-b = 2

b = -2

the equation of the line is

y = -2x - 2

y = mx + b

0 = (-2)(–1) + b

0 = 2 + b

-b = 2

b = -2

the equation of the line is

y = -2x - 2

Find the equation of a line with the given points. (Put your answers in the form y = mx + b.) (7, 2) (5, 4)
**Weegy:** you can follow these steps:
Given 2 points example.
Find the equation of the line thru the points (2,1) and (3,5)
- - - - - - - - - - -
This is a 2 step process. [ First find the slope of the line thru the points.
slope, m = diffy/diffx
m = (5-1)/(3-2)
m = 4
- - - - -
Now use y = mx + b with either point to find b, the y-intercept.
y = mx + b
5 = 4*3 + b
b = -7
- - - -
y = mx + b
y = 4x - 7 is the answer.
- - - - - - - - - - - -
Another approach using determinants:
|x y 1|
|2 1 1| = 0
|3 5 1|
- - - -
x(1-5) - y(2-3) + 1(10-3) = 0
-4x + y + 7 = 0
y = 4x - 7
