The slope-intercept equation is y=mx+b.
The slope formula is 
Our three points are (5,5), (-5,-7) and (0,-1)
Using our slope formula our slope becomes 
Then, if we use one of our points (pick whichever you want, although (0,1) is the easiest) to solve the equation. So, 
. When we solve for x and y, we get -1=0+b, or b=-1.
When we plug that back into the equation, we get.
Any angle that is bent at 45 degree, 90 degree,180 degree are called benchmark angles. Obtuse angle, Acute angle, Right angle, Straight angle are called benchmark angles
Answer:
The constant of variation k is 3/2.
The value of z is -30.
Step-by-step explanation:
As we know Function form is
Z=kxy-------------1
So for k
K = z/xy
So if z=18, x=2 y=6
k= 18/2 x6
k= 18/12
k=3/2
Now we have to find for z, now we know the value of x= -4 y =5 z =3/2
z= kxy
z= 3/2 (-4)(5)
z= -30
