Answer:
b. The graph of the new line is less steep than the graph of the original line, and the y-intercept has been translated up
Option b is right.
Step-by-step explanation:
Given that linear function f(x)=x is graphed on a coordinate plane.
The graph of a new line is formed by changing the slope of the original line to 2/3 and the y-intercept to 4.
The original slope was 1. Now changed to 2/3 i.e. slope is reduced. Hence the new line will be less steeper.
Also original line y =x has y intercept at the origin.
By changing y intercept to 4, we changed y intercept to upwards by 4 units.
Thus there is a vertical shift of 4 units.
b. The graph of the new line is less steep than the graph of the original line, and the y-intercept has been translated up
Option b is right.
A linear function is represented by a straight line.
The true statement is: (b) the graph of the new line is less steep than the graph of the original line, and the y-intercept has been translated up.
The function f(x) is given as:
[tex]\mathbf{f(x) = x}[/tex]
The attributes of the new function are:
So, the new function is:
[tex]\mathbf{f'(x) = \frac23x + 4}[/tex]
The slope of [tex]\mathbf{f(x) = x}[/tex] is 1.
2/3 is less than 1.
So, the new line is less steep
The y-intercept (4) means that:
The new line is shifted up by 4 units
Hence, the correct statement is: (b)
