The point-slope form:
We have
Therefore
<h3>slope = -3 and the point (-2, 6)</h3>------------
<h3>y + 2 = 2(x - 1)</h3>2x - y = 4 <em>it's standard form Ax + By = C</em>
y = 2x - 4 <em>it's slope-intercept form y = mx + b</em>
y - x = 4 →<em> </em>x - y = -4 <em>t's standard form Ax + By = C</em>
Disregard the 9x+3y in the pic. The answer is 3/4x-13/12=y
Alright, so it would be helpful to think about this question in terms of units. You're given a distance (meters) and speed (meters per second). You're asked for time (which is in seconds).
If you do
, your answer will be in seconds. So divide your distance (2.28 x 10^11 meters) by your speed (3.00 x 10^8 meters/second), and you should get your time!
If you do
