Parallel lines will have the same slope

y - y1 = m(x - x1)
slope(m) = 2
origin (0,0)...x1 = 0 and y1 = 0
now we sub

Find the midpoint between the points (-4, 2) and (-6, -2)
Zielflug [23.3K]

Answer:

c (-5, 0)

Step-by-step explanation:

midpoint formula:

( \frac{x1 + x2}{2} ) \: and \: ( \frac{y1 + y2}{2} )

x1 =  - 4\\ x2 =  - 6 \\ x1 + x2 =  - 4 +  - 6 \\  =  - 10

\frac{ - 10}{2}  =  - 5

y1 =  2 \\ y2 =  - 2 \\ y1 + y2 = 2 + ( - 2) \\  = 0

so, -5 is x and 0 is y. the answer is C.

A-3b=4;2a=6b-9 Answer by elimination. Please include how you got to the solution. Apparently there is a solution to this problem
AleksandrR [38]

Answer:

Step-by-step explanation:

a - 3b = 4 ---------------(eq1)

2a = 6b -9

or, 2a - 6b = -9 ------------(eq2)

    2a - 6b = 8 --------(eq1) X 2

   2a - 6b = -9 --------(eq2)

(-)       (+)       (+)

_________________________________

the variable part of both the equations are same. so the equation has more than one solution.
