Which of these z scores from a single distribution of scores corresponds to the raw score farthest from the mean of the distribution? –2.3
y=2x-0.5
Step-by-step explanation:
Given the expression of Δy in terms of Δx as;
Δy=4/2 Δx
Given y=2.5 and x =1.5 then substituting in the equation above will give;
y-2.5=2(x-1.5)
y-2.5=2x-3
y=2x-3+2.5
y=2x-0.5

Step-by-step explanation:
In order to check if the lines are perpendicular, we need to check if their slopes have the following relation (to find the slope we can use the slope-intercept form y = mx + b):
A.
In this option, y = -5 is an horizontal line and x = 2 is a vertical line, therefore they are perpendicular.
B.
First let's find the slope of each line:
These slopes obey the relation stated above, so the lines are perpendicular.
C.
These slopes obey the relation stated above, so the lines are perpendicular.
D.
These slopes obey the relation stated above, so the lines are perpendicular.
E.
These slopes don't obey the relation stated above, so the lines aren't perpendicular.
The correct options are A, B, C and D.
