How to Use Point Slope Form

The point-slope form is a method to find the equation of a line using a known slope and a point on the line. It is useful for graphing and solving word problems.

2.1 Step-by-Step Guide to Writing an Equation

Identify the slope ( m ) and a point ( (x_1, y_1) ) on the line.
Substitute these values into the point-slope formula:
[ y ⸺ y_1 = m(x ౼ x_1) ]
Simplify the equation to slope-intercept or standard form if needed.
Verify the equation by graphing or plugging in additional points.
This method ensures accuracy and versatility for various geometric applications.

2.2 Converting to Slope-Intercept Form

Converting point-slope to slope-intercept form involves algebraic manipulation. Start with the point-slope equation:
y ⸺ y1 = m(x ⸺ x1).
Distribute the slope:
y ⸺ y1 = mx ⸺ mx1.
Isolate y by adding y1 to both sides:
y = mx ౼ mx1 + y1.
Combine constants to get:
y = mx + b, where b = -mx1 + y1.
This process simplifies the equation for graphing and analysis.

2.3 Graphing a Line Using Point Slope Form

Graphing a line with point-slope form involves plotting the known point and using the slope to determine additional points. Start by marking the coordinate (x1, y1) on the graph.
