What is the equation of the line in the slope - intercept form a) y = 2x + 8 b) y = -8x + 2 c) y = -2 + 16 d) y = 16x - 2

y = -2x+16

Step-by-step explanation:

The line has a y intercept at 16  (This is where it crosses the y axis)

The slope is found by using

m = (y2-y1)/(x2-x1)

  We have two point (0,16)  and (8,0)

  m = (0-16)/ (8-0)

     = -16/8

     = -2

We can use the slope intercept form of a line

y= mx+b  where m is the slope and b is the y intercept

y = -2x+16

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
