Write the equation of the line that is perpendicular to the line y = 2x + 2 and passes through the point (6, 3).
Mama L [17]

For this case we have that by definition, the equation of the line in a slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

We have the following equation:

y = 2x + 2

Thus, the slope is m_ {1} = 2

By definition, if two lines are perpendicular then the product of the slopes is -1.

m_ {1} * m_ {2} = - 1

We findm_ {2}:

m_ {2} = \frac {-1} {m_ {1}}\\m_ {2} = \frac {-1} {2}

Thus, the equation of the line is:

y = - \frac {1} {2} x + b

We substitute the given point to find "b":

3 = - \frac {1} {2} 6 + b\\3 = -3 + b\\b = 6

Thus, the equation of a line perpendicular to the given line and passing through the given point is:

y = - \frac {1} {2} x + 6

Answer:

y = - \frac {1} {2} x + 6
