Question

Compare the different representations of linear functions.
On a coordinate plane, a line goes through points (0, 1) and (3, 0). Y = one-half x minus 1.

Identify the slope of the graphed line:
Identify the y-intercept of the graphed line:
Identify the slope of the line given by the equation:
Identify the y-intercept of the line given by the equation:

Answer 1

- Slope of the graphed line (through (0,1) and (3,0)): m = (0 − 1)/(3 − 0) = −1/3.
- Y‑intercept of the graphed line: y = 1 (point (0,1)).

- Slope of the line y = (1/2)x − 1: m = 1/2.
- Y‑intercept of the line y = (1/2)x − 1: y = −1 (point (0,−1)).
