Math Problem Statement
Using slope-intercept form, write an equation representing the line that has a slope of 3 and a y-intercept of (0, 5).
Solution
The slope-intercept form of a linear equation is given by:
where:
- is the slope of the line,
- is the y-intercept, which is the point where the line crosses the y-axis.
Given:
- Slope ,
- Y-intercept (from the point ).
Substitute these values into the slope-intercept equation:
Final Answer:
The equation of the line is:
