4. |
To graph the equation  by using the slope and y-intercept, you would ________. |
| |
|
A. |
graph the point at (–2, 0). Then go up 5 units and right 2 units. This will be the point at (0, 5). Then draw the line through points at
(–2, 0) and (0, 5). |

B. |
graph the point at (0, –2). Then go up 5 units and left 2 units. This will be the point at (–2, 3). Then draw the line through points at
(0, –2) and (–2, 3). |
| |
|
C. |
graph the point at (0, –2). Then go up 5 units and right 2 units. This will be the point at (3, 2). Then draw the line through points at
(0, –2) and (3, 2). |
| |
|
D. |
graph the point at (0, –2). Then go up 5 units and right 2 units. This will be the point at (2, 3). Then draw the line through points at
(0, –2) and (2, 3). |
