Part 1
Use the graphing tool on the right to graph the line.

Answer 1

The line is y = x + 7.

Key facts:
- Slope = 1 (rise 1, run 1).
- y-intercept = 7 → point (0, 7).
- x-intercept: set y = 0 → x = −7 → point (−7, 0).

Points you can plot: (−7, 0), (−3, 4), (0, 7), (1, 8), (2, 9). Then draw a straight line through those points.

Quick steps for the graphing tool:
1. Plot (0, 7).
2. From (0,7) go right 1 and up 1 to place (1,8); repeat to get another point, or go left 1 and down 1 to (−1,6).
3. Draw the line through the plotted points, extending across the grid.

(If helpful: the line crosses the y-axis at 7 and the x-axis at −7.)
