Find parametric equations through point P=(2,2,7) in the direction of the vector v = (44, 14, -20)?
ycow [4]

9514 1404 393

Answer:

  (x, y, z) = (2+44t, 2+14t, 7-20t)

Step-by-step explanation:

One way to write parametric equations for line L is ...

  L = P + t·<em>v</em>

where P is the given point and <em>v</em> is the given direction vector. Using that form, we have ...

  (x, y, z) = (2+44t, 2+14t, 7-20t)

__

If you like, you can remove a common factor of 2 from the coefficients of t.

  (x, y, z) = (2+22t, 2+7t, 7-10t)

What is the slope and y-intercept for the graph of the equation<br><br> Y= 4/5 x - 3 ?
vichka [17]
So,

The slope-intercept form is as follows:
y = mx + b

"m" is the slope, and "b" is the y-intercept.  The y-intercept for this equation is (0,b).

Our equation is y= \frac{4}{5} x-3

That means that \frac{4}{5} is the slope, and -3 is the y-intercept.
