(9-15)/(-2+4)= -6/2 = -3
-3 is the slope
Hi!
We can use <u>point-slope form </u>to solve this.

<em> and </em>
<em> will be from one of the points.</em>
<u>First, we have to find </u>
<u>, the slope. We can use the slope equation to get this.</u>

<em>Plug in your points:</em>

Your slope is 
<u><em>Now plug points and slope into point-slope equation. We will use (8, 4).</em></u>

Now, if you want to get it into y = mx + b form, you have to solve for y:



Your equation is

X+y+z=92
y=3x
z=2x-10
subsitute
x+3x+2x-10=92
6x-10=92
add 10 to both sdies
6x=102
divide by 6
x=17
subsitute
y=3x
y=3(17)
y=51
z=2x-10
z=2(17)-10
z=34-10
z=24
x=17
y=51
z=24
the numbers are 17,51,24
Answer:7/8 of an inch
