Question 239341
You plot some selected points for x and then calculate the y value and then plot the points on the graph and then draw a straight line through the points.


Example:


When x = 0, y = 0


When x = 10, y = 10


Plot (x,y) = (0,0) on the graph.


Plot (x,y) = (10,10) on the graph.


Draw a straight line between them.


There's your graph.


The point (x,y) is x units to the right or left of x = 0, and y units up or down from y = 0.


If x is negative, you move to the left.


If y is negative, you move down.


If x is positive, you move to the right.


If y is positive, you move up.


A graph of your equation looks like:


{{{graph(600,600,-15,15,-15,15,x)}}}
