Math Problem Statement
The equation of line s is y= – 4x– 5 3 . Line t includes the point ( – 3,3) and is parallel to line s. What is the equation of line t?
Solution
To find the equation of line , we follow these steps:
-
Identify the slope of line : The equation of line is given as: The slope () of line is .
Since line is parallel to line , its slope will also be .
-
Use the point-slope form of the line equation: The point-slope form is: where is a point on the line, and is the slope.
For line , the given point is and the slope is .
Substituting these values into the point-slope form:
-
Simplify the equation: Expand the right-hand side: Add 3 to both sides to isolate :
So, the equation of line is:
Final Answer:
The equation of line is:
