Math Problem Statement
Write the slope-intercept form of the equation with slope 3 and y-intercept -2. Slope-intercept form: y = mx + b
Solution
The slope-intercept form of a line is:
Where:
- is the slope,
- is the y-intercept.
Given:
- Slope ,
- Y-intercept .
Substitute these values into the slope-intercept form:
Correct Answer:
The correct choice is "y = 3x - 2".
