Consider the graph of the linear function [tex]h(x) = -\frac{2}{3} x + 5[/tex]. Which change would move the graph down 3 units?

A. Change the value of [tex]b[/tex] to -3
B. Change the value of [tex]m[/tex] to -3
C. Change the value of [tex]b[/tex] to 2
D. Change the value of [tex]m[/tex] to 2



Answer :

Let's analyze the given linear function [tex]\( h(x) = -\frac{2}{3} x + 5 \)[/tex].

To understand how to move the graph down by 3 units, let's focus on the part of the equation that is responsible for shifting the graph vertically. This part is the constant term, [tex]\( b \)[/tex], which in this case is 5.

When you change the value of [tex]\( b \)[/tex], it affects the vertical position of the graph without affecting its slope.

To move the graph down by 3 units, we need to subtract 3 from the current value of [tex]\( b \)[/tex]:

[tex]\[ b = 5 - 3 = 2 \][/tex]

So, the new equation of the function after this change becomes:

[tex]\[ h(x) = -\frac{2}{3} x + 2 \][/tex]

This modifies the vertical position of the graph by shifting it downward by 3 units.

Therefore, the correct change to move the graph down by 3 units is to change [tex]\( b \)[/tex] to 2. This means the correct answer is:

- The value of [tex]\( b \)[/tex] to 2
