To find: The parametric equation for the lines
Answer to Problem 30E
The parameter equation which satisfies the given conditions is
Explanation of Solution
Given:
The slope -2and the point (-10,-20)
Calculation:
Start at the point (-10,-20) and move up and to the right along with the line.
Because the line has slope -2, for every 1 unit, move to the right, move up -2 u its.
In other words if x coordinates is increased by t units, correspondingly decrease the y coordinates by
Thus, using the above information,
Therefore, the parameter equation which satisfies the given conditions is
Conclusion:
Therefore, the parameter equation which satisfies the given conditions is
