Question

Write an equation of the line that passes through (7,10) and is perpendicular to the line y=1/2x−9

Answer 1

Answer:

Step-by-step explanation:

Since the new line is perpendicular to y=1/2x−9 so slope of new line is opposite reciprocal of this line i.e -2. So equation of new line will be y = -2x + c . And this line passes through (7,10). So by putting this points we get the value of c.

10 = -2*7 + c

c = 24

Therefore new line is y= -2x + 24.
