Question

How many solutions does the system have? y = 3x + 9 y = -1/2x - 1

Answer 1

they are lines with different slope, so once

Answer 2

same slope different y intercept = never cross
same slope same intercept = same line = intersect infinite times
different slope = intersect once.

Answer 3

true...learn this

same slopes, different y intercepts....parallel lines....0 solutions
same slope, same y intercept....infinite solutions
different slopes, different y intercepts...1 solution

Answer 4

oh....de ja vous

Answer 5

there must be an echo in here:P

Answer 6

lol

Answer 7

just playin...leave it. you said it different and that might help

Answer 8
