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.
