Slope-Intercept Form:
| From: | To: |
The slope-intercept form is a way of writing linear equations and inequalities. It is expressed as y = mx + b, where m represents the slope of the line and b represents the y-intercept. For inequalities, this form helps visualize the solution set on a coordinate plane.
The calculator converts given parameters into slope-intercept form inequality:
Where:
Explanation: The calculator takes the slope, intercept, and inequality type to generate the proper slope-intercept form representation.
Details: Slope-intercept form is crucial for graphing linear equations and inequalities, understanding the relationship between variables, and solving systems of equations. It provides immediate visual information about the line's steepness and where it crosses the y-axis.
Tips: Enter the slope (m) and y-intercept (b) values, then select the appropriate inequality symbol. The calculator will generate the inequality in proper slope-intercept form.
Q1: What does the slope represent?
A: The slope (m) represents the rate of change between the dependent and independent variables, indicating how much y changes for each unit change in x.
Q2: What is the y-intercept?
A: The y-intercept (b) is the point where the line crosses the y-axis, representing the value of y when x equals zero.
Q3: How do I graph an inequality in slope-intercept form?
A: First graph the boundary line y = mx + b, then shade the appropriate region based on the inequality symbol (> shade above, < shade below).
Q4: Can this calculator handle fractions?
A: Yes, the calculator accepts decimal values for slope and intercept, which can represent fractional relationships.
Q5: What's the difference between equation and inequality forms?
A: Equations represent exact relationships (y = mx + b), while inequalities represent ranges of possible solutions (y > mx + b or y < mx + b).
