Question 2 of 10

Which ordered pair represents the [tex]y[/tex]-intercept of the graph of the equation [tex]y = -4x - 7[/tex]?

A. [tex](0, -7)[/tex]

B. [tex](-4, 0)[/tex]

C. [tex](0, -4)[/tex]

D. [tex](-7, 0)[/tex]



Answer :

To determine the y-intercept of the graph of the equation [tex]\( y = -4x - 7 \)[/tex], we need to identify the point where the graph crosses the y-axis. This occurs when the value of [tex]\( x \)[/tex] is zero.

1. First, set [tex]\( x = 0 \)[/tex] in the equation [tex]\( y = -4x - 7 \)[/tex]:
[tex]\[ y = -4(0) - 7 \][/tex]

2. Simplify the expression:
[tex]\[ y = 0 - 7 \][/tex]
[tex]\[ y = -7 \][/tex]

3. The ordered pair representing the y-intercept is where [tex]\( x = 0 \)[/tex] and [tex]\( y = -7 \)[/tex]:
[tex]\[ (0, -7) \][/tex]

Thus, the correct ordered pair is [tex]\( (0, -7) \)[/tex].

So, the answer is:
A. [tex]\( (0, -7) \)[/tex]
