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 (2,5)(-2, 5), follow these steps:

1. Identify the Slope-Intercept Form of a Line:

The equation of a line can be written as: y=mx+by = mx + b where mm is the slope, and bb is the y-intercept.

2. Use the Given Information:

We know:

  • The slope m=3m = 3
  • The line passes through the point (2,5)(-2, 5), which we will use to solve for the y-intercept bb.

3. Find the y-Intercept:

Substitute the point (2,5)(-2, 5) into the slope-intercept form: 5=3(2)+b5 = 3(-2) + b 5=6+b5 = -6 + b b=5+6=11b = 5 + 6 = 11 So, the equation of the line is: y=3x+11y = 3x + 11

4. Plot the Line:

  • Plot the point (2,5)(-2, 5) on the graph.
  • Since the slope is 3, which means "rise over run" is 3/13/1, move 3 units up and 1 unit to the right from the point (2,5)(-2, 5) to find another point on the line.
  • Continue this pattern or use the equation y=3x+11y = 3x + 11 to plot other points like (0,11)(0, 11) or (1,14)(1, 14).

  2. What is the general form of a linear equation?
  3. How can you convert a linear equation from slope-intercept form to standard form?
  4. How would the line change if the slope were negative?
  5. How do you graph vertical and horizontal lines?

Tip: Remember, slope mm is the ratio of how much the line rises vertically compared to how much it moves horizontally.
