4y-5x=20
. Just give numbers for x or y . Then, find the x value or y value from the equation.
Remember that y-axis is the vertical and x-axis is the horizontal line.
For example, just give x = 0 . 4y=20 y = will be 5 .
Now, write these on your graph.
As you see, 0 means orijin point , but if y=5 , use vertical line for writing 5.
Then, find the values while x=1 , x=2 ,and also x= -1 , x= -2 .
Finally, find the points from the connection of x and y points.
Then, combine all of connected points as a curve .
