The slope of the line below is -3. Which of the following is the point-slope form of the line?
-5
5
• (2,-2)

Given:

The slope of the line is -3.

The line passes through the point (2,-2).

To find:

The point-slope form of the line.

Solution:

Point slope form: If a line passes through the point with slope m, then the point-slope form of the line is:

The slope of the line is -3 and it passes through the point (2,-2). So, the point-slope form of the line is:

Therefore, the required point slope form of the given line is .

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
