If [tex]$y=2x+7$[/tex] were changed to [tex]$y=\frac{1}{2}x+7$[/tex], how would the graph of the new function compare with the original?

A. It would be shifted down.
B. It would be less steep.
C. It would change orientation and slant down.
D. It would be steeper.



Answer :

Let's analyze the given functions step-by-step to determine how the graph of the new function compares with the original one.

The original function is:
[tex]\[ y = 2x + 7 \][/tex]
This equation is in the slope-intercept form [tex]\( y = mx + b \)[/tex], where [tex]\( m \)[/tex] represents the slope and [tex]\( b \)[/tex] represents the y-intercept.

For the original line:
- The slope [tex]\( m \)[/tex] is [tex]\( 2 \)[/tex].
- The y-intercept [tex]\( b \)[/tex] is [tex]\( 7 \)[/tex].

The new function is:
[tex]\[ y = \frac{1}{2}x + 7 \][/tex]
This is also in the slope-intercept form.

For the new line:
- The slope [tex]\( m \)[/tex] is [tex]\( \frac{1}{2} \)[/tex].
- The y-intercept [tex]\( b \)[/tex] remains [tex]\( 7 \)[/tex].

Now, let's compare the slopes of the two lines:
- The slope of the original line is [tex]\( 2 \)[/tex].
- The slope of the new line is [tex]\( \frac{1}{2} \)[/tex].

Since [tex]\( \frac{1}{2} \)[/tex] is less than [tex]\( 2 \)[/tex], it means that the new line will have a smaller slope. A smaller slope indicates that the new line is less steep compared to the original line.

Therefore, the graph of the new function [tex]\( y = \frac{1}{2}x + 7 \)[/tex] would be less steep than the graph of the original function [tex]\( y = 2x + 7 \)[/tex].

So, the correct answer is:
B. It would be less steep.
