Part 1: Create an equation of a line in point-slope form. Be sure to identify all parts of the equation before writing the equation.

Part 2: Using the equation of the line you wrote in part 1, write an equation of a line that is perpendicular to this line.

Answer with explanation:

Part--1:

We know that a equation in point-slope form is represented by:


y-y_1=m(x-x_1)

where m is the slope of the line and
(x_,y_1) is a point through which the line passes.

Consider a equation in a point-slope form as:


y-5=2(x-1)

This means that the slope of the line is: 5

and the line passes through the point (1,5).

Part--2:

Now as we know that if a line has a slope as m then the perpendicular line has a slope: -1/m

Since,


m* \text{Slope\ of\ second\ line}=-1\\\\i.e.\\\\\text{Slope\ of\ second\ line}=(-1)/(m)

Let this perpendicular line passes through (2,6)

Hence, the equation of a line in point slope form is given by:


y-6=(-1)/(2)(x-2)
