Answer:
x-int: (3, 0)
y-int: (0, -3)
General Formulas and Concepts:
Alg 1
Slope-Intercept Form: y = mx + b
The y-intercept is the y value when x = 0.
Another way to reword that is when the graph crosses the y-axis.
The x-intercept is the x value when y = 0.
Another way to reword that is when the graph crosses the x-axis.
Step-by-step explanation:
Step 1: Define equation
x - y = 3
Step 2: Convert to slope-intercept form
- Subtract x on both sides: -y = 3 - x
- Divide both sides by -1: y = x - 3
Step 3: Find x/y-intercepts
x-int
- Set y = 0: 0 = x - 3
- Add 3 to both sides: 3 = x
- Rewrite: x = 3
- Write coordinates: (3, 0)
y-int
- Set x = 0: y = 0 - 3
- Subtract: y = -3
- Write coordinates: (0, -3)
