for graphing:
y =10x +40
some points would be:
(-3,10), (0,40), and (3,70)
yes.
To graph the equation y = 10x + 40, you can follow these steps:
1. Set up a coordinate system with x and y axes.
2. Plot the given points (-3, 10), (0, 40), and (3, 70) on the graph.
- For the point (-3, 10), find the x-coordinate, which is -3, and locate it on the x-axis. Then find the y-coordinate, which is 10, and locate it on the y-axis. Mark the point of intersection.
- Repeat the same process for the other two points.
3. Once you have the three points plotted, draw a straight line passing through them. Ensure that the line reasonably covers the region of the graph.
- If required, you can choose additional points on the line to verify its accuracy.
In this case, the three given points form a straight line. Hence, you can directly connect them to obtain the graph of y = 10x + 40.
