​.

Use the line tool and select two points on the line to graph the line.

Initial graph state
Graph has a background image with description "".
The horizontal axis goes from -10.8 to 10.8 with ticks spaced every 1 unit(s).
The vertical axis goes from -10.8 to 10.8 with ticks spaced every 1 unit(s).

Answer 1

I can’t draw directly here, but do this in the graph tool:

1. Choose the line (or two-point) tool.
2. Plot two points that lie on y = −3x + 2. Good easy choices:
- Point A: (0, 2) (y-intercept)
- Point B: (1, −1) (one right, three down from A)
3. Click at (0,2) then click at (1,−1). The tool will draw the line through those two points.
4. Optional check: another point on the line is (−1, 5) or (2, −4); the drawn line should pass through them.

Tip: slope = −3 means for every +1 in x, y decreases by 3.
