Concept explainers
To find: The timing at which Slope intercept form, point slope form and standard form are used.
Answer to Problem 39PPE
This can be used to solved the linear equations.
Explanation of Solution
Given:
Slope intercept form, point slope form and standard form.
Concept used:
The point slope form of an equation of a non-vertical line with slope
The slope-intercept form of a linear equation of a non-vertical line is:
Here
Calculation:
Consider the following point slope form of a linear equation:
The point slope form of an equation of a non-vertical line with slope
This can be used when a point and slope of the line is given.
Consider the following slope intercept form of a linear equation:
The slope-intercept form of a linear equation of a non-vertical line is:
Here
This formula can be used when slope and the
Consider the following standard form of a linear equation:
The standard form of a linear equation is:
Here,
Hence, this can be used to solved the linear equations.
