May you state whether the two lines are parallel, perpendicular or neither. y = 4x + 6; 16x - 4y = 12

Fynjy0 [20]

Answer: These lines are parallel

Step-by-step explanation: There are two equations. y=4x+6, and the second one equals y=4x-3. Because they have the same slope, they are parallel.

What is the midpoint of this point (-4,2) and (8,0)?

marissa [1.9K]

Answer:

Mid - point = ( 2 , 1 )

Step-by-step explanation:

Let A = ( - 4 , 2 ) and B = ( 8 , 0 )

Let P = ( x , y ) be the mid-point of AB

Then,

$P = (\frac{x_A + x_B}{2} , \frac{y_A + y_B}{2} ) \\\\P =(\frac{-4+8}{2} , \frac{2+0}{2}) \\\\P = ( \frac{4}{2} , \frac{2}{2} )\\\\P = ( 2 , 1)$

What is the equation of the line containing points 7,3 14,6 and 21,9

oksian1 [2.3K]

Let's present a solution for the generic case.
The equation will be of the form y=ax+b

If (7,3) is on it, then 3=7a+b
If (14,6) is on it, then 6=14a+b

Now we have a system we can solve.

3=7a+b => b = 3-7a
6=14a + 3-7a => 3 = 7a => a=3/7

b = 3-7*3/7 = 0

So y = (3/7)x is the equation.
