Question 2 of 10

The point-slope form of a line is [tex]y + y_1 = m \left( x + x_1 \right)[/tex], where [tex]m[/tex] is the slope and [tex](x_1, y_1)[/tex] is a point on the line.

A. True
B. False



Answer :

To solve this question, let's closely examine the given point-slope form of a line to determine its correctness. The point-slope form of a line should correctly represent the relationship between a point on the line, its slope, and another point on the line.

The standard point-slope form of a line is given by:

[tex]\[ y - y_1 = m(x - x_1) \][/tex]

Where:
- [tex]\( m \)[/tex] is the slope of the line
- [tex]\((x_1, y_1)\)[/tex] is a specific point on the line

Now, let's compare this with the form provided in the question:

[tex]\[ y + y_1 = m(x + x_1) \][/tex]

By comparing both forms, we can see some differences.

1. In the standard form, the left side of the equation has [tex]\( y - y_1 \)[/tex], while in the provided form, it has [tex]\( y + y_1 \)[/tex].
2. On the right side of the equation, the standard form has [tex]\( (x - x_1) \)[/tex], while the provided form has [tex]\( (x + x_1) \)[/tex].

These differences indicate that the provided form in the question is not consistent with the standard point-slope form of a line.

To summarize:
- The given form [tex]\( y + y_1 = m(x + x_1) \)[/tex] is incorrect.

Thus, the correct answer to the question is:

B. False
