y = x − 3 f or x = 0 → y = 0 − 3 = − 3 → A ( 0 ; − 3 ) f or x = 3 → y = 3 − 3 = 0 → B ( 3 ; 0 )
Draw a line crossing through -3 on the y axis (3 under the middle, or the origin) and then draw a straight line that crosses through exactly one square on the graph from corner to corner. ;
To sketch the graph of y = x − 3 , identify points such as the y-intercept ( 0 , − 3 ) and another point like ( 3 , 0 ) . After plotting these points, draw a straight line to represent the equation. The line will have a positive slope, rising from left to right.
