To find the line perpendicular to y = 13x − 8 and passing through (0, 7), follow these steps:
Identify the slope of the given line y = 13x − 8:
The slope m is 13.
Determine the slope of the perpendicular line:
The slope of the line perpendicular to a line with slope 13 is the negative reciprocal. Thus, it is .
Use the point-slope form to find the equation of the perpendicular line passing through (0, 7):
The point-slope form is:
Here, () is (0, 7) and m is .
Substitute these values:
