Parallel line means having the SAME slope

so the slope of a line parallel to the given line is 2

plug in the given point and slope of 2 into point slope form
y+1 = 2 (x+4)

solve for slope intercept form
y+1 = 2x + 8
y = 2x + 7

answer: y=2x+7

If M is the midpoint of line segment XY, find the coordinates of X if M(-3,1) and Y(-8,4)
lozanna [386]

Answer:

The coordinates of point X are (-11/2, 5/2)

Step-by-step explanation:

To find the coordinates of X , we shall apply the midpoint formula;

Mathematically, that would be;

(x , y) = (x1 + x2)/2 , (y1 + y2)/2

From the question

x1 = -3 , x2 = -8

y1 = 1 , y2 = 4

So substituting these values, we have;

(x ,y) = (-3-8)/2, (1 + 4)/2

(x ,y) = -11/2, 5/2

A passenger train left Austin, Texas at 12:00 PM bound for Dallas, exactly 210 miles away; it traveled at a steady 50 miles per
olya-2409 [2.1K]

Answer:

  1. 3 hours
  2. 1 hour 45 minutes
  3. 300 miles

Step-by-step explanation:

1. The trains are moving toward each other at a total speed of 50 +20 = 70 miles per hour. Together, they cover the 210 mile distance in ...

  time = distance/speed

  time = 210 mi/(70 mi/h) = 3 h

The trains collide after 3 hours.

__

2. The fly is closing with the freight train at a speed of 100 +20 = 120 miles per hour. Together, the fly and the train cover the initial 210 mile distance in ...

  (210 mi)/(120 mi/h) = 7/4 h = 1 hour 45 minutes

The fly first meets the oncoming freight train after 1 h 45 min.

__

3. The fly is flying for all three hours before the trains collide, so, at 100 miles per hour, will fly 300 miles.
