Question

would u know where these 2 linear equations intersects? if it does?....2x-y=-2 and y=2x+4

Answer 1

2x - y = -2 <=> y = 2x + 2 vs. y = 2x + 4
You have two parallel lines intersecting the y-axis at two different points, so no they will not intersect.

Answer 2

can you please how did u arrive to that solution? do i need to know what is x and y?

Answer 3

It would be easier if you just plotted the two lines by hand.
Start by plugging in x = -5 into both equations and checking the resulting y value.
Then do x = -4, -3, ..., 0, 1, 2, ...5.
You'll see that they are parallel.
Also, both lines have the same slope ( the ratio of y to x ) so they will be parallel.

Answer 4

You can get slope by looking at the a in the equation y = ax + b.
The slope of those two lines is a = 2.

Answer 5

so meaning to say, i dont need to compute and find the equivalent of x and y?

Answer 6

i dont really understand...would you mind..i still have 4 more? can u help me?

Answer 7

please

Answer 8

I'll take a look at one more, sure

Answer 9

x-5y=15 and x+ 5y=-5

Answer 10

would u mind doing it step by step for me to follow you? :) pleasee

Answer 11

Ok, solving for the first equation you see that x - 5y = 15 <=> 5y = x - 15
Plug this into the second equation x + 5y = -5
You get x + ( x - 15 ) = -5
Simplify and you get 2x = 10, x = 5
Plug x = 5 into either of the equations to get y = - 2

Answer 12

Therefore, the two lines intersect at x = 5, y = 2 ( 5, - 2 )

Answer 13

what the pairs?

Answer 14

are you still therE?

Answer 15

Yes, what do you mean?

Answer 16

pairs like for me to get where it intersects...

Answer 17

There is only one point at which it intersects.

Answer 18

Two straight lines can only intersect at one point on a flat 2D surface.

Answer 19

ok..i will just review what you just typed later...can you still answer 2 more?

Answer 20

2x-3y=6 and 6x=18+9y

Answer 21

just so amazed by your answers...

Answer 22

thank you for helping me with the first 2

Answer 23

still around?

Answer 24

hello...?
