Question

determine whether the lines are parallel,intersect,or coincide.
Y=2x+5
Y=2x-1

Y=5x-2
X+4y=8

Y=1\3x+4
X-3y=-12

5y+2x=1
Y=-2\5x+3

Answer 1

did you graph this before ??

Answer 2

hint: if two equation have same slope then its parallel

Answer 3

No because it didnt say to graph and is 1. Slope?

Answer 4

ok but you can graph to check
yes first two equation have same slope so what is that ??

Answer 5

2right??

Answer 6

first two equation are parallel because they both have same slope :))

Answer 7

2nd two equation
you have to solve 2nd equation for y can you do that ??

Answer 8

Is 2.intersect

Answer 9

yep right
what about third one ??

Answer 10

Coincide??

Answer 11

yep right
coincide because
same slope
same y-intercept

Answer 12

4.also coincide??

Answer 13

did you solved first equation for y

Answer 14

??????? :) :) :) :)

Answer 15

let me know then we can solve together :) :) :)

Answer 16

No I did not solve for the first equation

Answer 17

ok if you can then you can see its not Coincide
lets solve that first :)

Answer 18

Okay

Answer 19

subtract 2x both side
let me know what you get after that ??
