Question

solve by graphing 2x=y+1 2x-y=5

Answer 1

they wont have any solutions lfthese are straigth line equation and parallel lines

Answer 2

how do the lines loook like

Answer 3

jackie they shld be shown on a graph .. would be better to explain u

Answer 4

there not shown on a graph they just give that equation and say to graph it

Answer 5

where would the points go

Answer 6

look these are two lines which should be drawn tats y i was askin u to come there

Answer 7

i was there u werent

Answer 8

come back i was on some other question

Answer 9

send me the link again

Answer 10

solve the equations into "y = mx + b" format. b is the y-intercept. m is the slope. Using this info, you should be able to draw the 2 lines on a graph, and the solution is where they cross.

Answer 11

the lines are parallel because they have same gradient

Answer 12

My bad. Nick is right. When you solve for y, you get y = 2x - 1 and y = 2x - 5. You can graph those, and you'll see they're parallel because they have the same slope. So there is no solution. You can also see this by substituting "y+1" for "2x" in the second equation, which makes "y + 1 - y = 5," which simplifies to "1 = 5," which is impossible.
