Question

1. what is the equation of the line? graph of a line on a coordinate plane

Explanation:

Step1: Find intercepts

The line crosses y-axis at $(0,3)$ (y-intercept $b=3$) and x-axis at $(3,0)$.

Step2: Calculate slope

Slope $m = \frac{0-3}{3-0} = -1$

Step3: Write equation

Using $y = mx + b$: $y = -x + 3$

Answer:

$y = -x + 3$
