1. Examples
1. Draw a line with slope = 3 and point = (4,5)
Solution:
Step 1: Plot the first point color{green}{(4,5)}
Step 2: Find second point by using the slope
m="rise"/"run"=3/1
:."rise"=3 and "run"=1
From (4,5), Plot the point that is 3 units up and 1 unit right.
We get the second point as (4+1,5+3)=(5,8).
So, plot the second point color{blue}{(5,8)}
Step 3: Draw a line through these two points (4,5) and (5,8)
2. Draw a line with slope = 4 and point = (-5,6)
Solution:
Step 1: Plot the first point color{green}{(-5,6)}
Step 2: Find second point by using the slope
m="rise"/"run"=4/1
:."rise"=4 and "run"=1
From (-5,6), Plot the point that is 4 units up and 1 unit right.
We get the second point as (-5+1,6+4)=(-4,10).
So, plot the second point color{blue}{(-4,10)}
Step 3: Draw a line through these two points (-5,6) and (-4,10)
3. Draw a line with slope = -5 and point = (6,7)
Solution:
Step 1: Plot the first point color{green}{(6,7)}
Step 2: Find second point by using the slope
m="rise"/"run"=-5/1
:."rise"=-5 and "run"=1
From (6,7), Plot the point that is 5 units down and 1 unit right.
We get the second point as (6+1,7-5)=(7,2).
So, plot the second point color{blue}{(7,2)}
Step 3: Draw a line through these two points (6,7) and (7,2)
4. Draw a line with slope = 6 and point = (7,-8)
Solution:
Step 1: Plot the first point color{green}{(7,-8)}
Step 2: Find second point by using the slope
m="rise"/"run"=6/1
:."rise"=6 and "run"=1
From (7,-8), Plot the point that is 6 units up and 1 unit right.
We get the second point as (7+1,-8+6)=(8,-2).
So, plot the second point color{blue}{(8,-2)}
Step 3: Draw a line through these two points (7,-8) and (8,-2)
