# Find the slope of the line that isa) parallel to the line containing a ,   0 and 0 ,   b .b) perpendicular to the line through a ,   0 and 0 ,   b .

To determine

(a)

To find:

The slope of the line that is parallel to the line containing a, 0 and 0, b.

Explanation

Let the slope of the line containing the two given points be m1.

Let the slope of the unknown line be m2.

First find the slope of the line containing the two given points.

x1,y1=a, 0

x2,y2=0, b

Formula for slope of the line containing two points.

Slope is denoted by m.

m1=y2-y1x2-x1

Here x1x2

Substituting the x and y co-ordinates

To determine

(b)

To find:

The slope of the line that is perpendicular to the line through a, 0 and 0, b.
