Find the slope of the line that passes through each pair of points.
6. E(6, 8), F(6, –2)

slope is undefined

Step-by-step explanation:

Calculate the slope m using the slope formula

m =

with (x₁, y₁ ) = E(6, 8) and (x₂, y₂ ) = F(6, - 2)

m = = ← undefined

Since division by zero is undefined then the slope is undefined.

This means the line is vertical and parallel to the y- axis

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

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.
