Answer to Problem 20T
The equation of parallel line is
Explanation of Solution
Given:
The coordinates of point is
Formula used:
The formula of slope-intercept form of line is,
Where
m is slope of line.
b is y-intercept of line.
Calculation:
Solve the given line in slope-intercept form.
Compare the above equation with formula to get the value of slope that is,
Two non-vertical lines are parallel if their slopes are equal so that the slope of parallel line is also
The
Substitute
Thus, the equation of parallel line is
(b)
To find: The equation of line through given conditions.
(b)

Answer to Problem 20T
The equation of line is
Explanation of Solution
Given:
The x-intercept of line is 6 and y-intercept is 4.
Calculation:
The intercepts give the two points of line that is
The formula to find the slope of line passes through two given points is,
In the above formula
Substitute 4 for
Use the point-slope form to get the equation of line, and the formula is,
Substitute 0 for
Thus, the equation of line is
