What is the slope of the line that passes through the points -(9, -5) and (-1, -9)?

-1/2

Step-by-step explanation:

I''m guessing the first coordinate is supposed to be (-9,-5) instead of -(9,-5).

Slope is calculated by

I'll use (-9,-5) as the first coordinate and (-1,-9) as the second.

Fill in the numbers and you get:

Simplify the double negatives:

Simplify again:

Simplify one last time (divide both sides by 4): (aka )

395.84

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
