Find the parametric equation for the line where the planes -7x + 7y - z = 20 and 2x + 7y + 2z = 23 intersect. r(t) = + t There are two possible answers <0, 3, 1> or <21, 12, -63>. Show me your work how you can have either of the answers by using a math editor or uploading the image of your work.

Find parametric equations for the line of slope 2 that passes through the point 13, 52 .

* Subscribe An object is thrown in the air with vertical velocity of 20 ft/s and horizontal velocity of 15 ft/s. The object's height can be described by the equation y (t) = -162+20t while the object moves horizontally with constant velocity 15 ft/s. Write parametric equations for the object's position, and then eliminate time to write height as a function of horizontal position. How did you arrive at your conclusion(s) for this problem? *Provide your initial post, read posts from your classmates, and contribute to the discussion by responding (with a minimum of 3 sentences). You may collaborate together to complete the solution. Your response should be well thought out and further the discussion. Use the graphical equation editor when necessary to express your answer.
