Question

sketch the graphs of each of the following fuunction
4x-2y+9=0

Answer 1

First, draw a table to locate few point satisfying the equation
x | 0 | 1 | 2 | 3 |
y |9/2 |13/2 |17/2 |21/2|
Then draw the x-axis and mark the points you found on the graph.
After that, draw a straight line to join the point
Finally, you 've finished plotting the graph

Answer 2

Or, if you think that's troublesome, you can put x=0, and y=0 into the equation to find the y-int, and x-int respectively. Then. draw a straight line to join the two points and you can also finish plotting the graph
