Question

Solve the system by graphing. Tell weather the system has one solution, infinitely many solutions or no solutions.
y=x+5
y=x-1

Answer 1

Please help.

Answer 2

What is the slope of y = x+5?

Answer 3

1

Answer 4

What is the slope of y = x -1?

Answer 5

also 1

Answer 6

What do you know about lines that have the same slope?

Answer 7

they have many solutions?

Answer 8

Those lines have the same slope. What can you say about them?

Answer 9

they are parallel

Answer 10

How many points do parallel lines have in common?

Answer 11

none

Answer 12

so it's no solutions

Answer 13

Bingo

Answer 14

Could you show me how to graph the equations though

Answer 15

What is the y intercept of y = x + 5?

Answer 16

5?

Answer 17

Mark 5 on the y axis.

Answer 18

ok, so good so far

Answer 19

You already said the slope is 1 which is 1/1 which means rise 1 and run 1.

Answer 20

So from the point you marked on the y axis rise 1 and go right 1.

Answer 21

I see what you did there(: Go on
