question on how to read a fraction correctly?

the bulb shutter velocity skill the shutter continues to be open for as long as you carry the button down. you ought to use that for doing long exposures at night/in the lifeless of night or low easy. i've got faith the numbers with " mean seconds, aka 2" is two seconds. the numbers without " often mean a million/x, as in 10 is a million/10 of a 2d. i've got not truly seen ones with decimals like a million.3, so i'm no longer completely particular approximately that. and the f-stops replace how huge open your shutter is. f3.5 is particularly huge open and we could in multiple sunshine. f22 is the different, letting in little or no easy. shutter velocity and f-stops paintings inversely. so a decrease f-stop like 3.5 will maximum in all likelihood require a quicker shutter velocity.

That means the whole fraction is negative. (Which actually works out the same as a negative top number.)

y = - 3/2x + 3

y intercept = 3(0,3)

Slope is - 3/2 or - 1.5

go down 1.5 for eachx number

(0,3) and (1,1.5) and (2,0) ,(3 - 1.5) (4, - 3) etc....
