Math Problem Statement
Graph the line with slope 3 passing through the point (-2, 5).
Solution
To graph the line with a slope of 3 passing through the point , follow these steps:
1. Identify the Slope-Intercept Form of a Line:
The equation of a line can be written as: where is the slope, and is the y-intercept.
2. Use the Given Information:
We know:
- The slope
- The line passes through the point , which we will use to solve for the y-intercept .
3. Find the y-Intercept:
Substitute the point into the slope-intercept form: So, the equation of the line is:
4. Plot the Line:
- Plot the point on the graph.
- Since the slope is 3, which means "rise over run" is , move 3 units up and 1 unit to the right from the point to find another point on the line.
- Continue this pattern or use the equation to plot other points like or .
