Find the distance between point E and point F

6

Step-by-step explanation:

There are two ways to do this. (You could also use the distance formula, but because the x coordinates are the same, these are the two easiest ways).

Method 1: counting.

Count the distance. This is shown in the picture attached. This is the easiest way to do it.

Method 2: solve.

the two coordinates of the points are (-3,3) and (-3,-3). Because the x value is the same, (x,y), you can subtract the y values: 3- (-3) = 6.

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.

step-by-step explanation:

mean or average is 40.6
