Question

Help pleaseee algebra 1- ill give you a lot of medals and ill fan if you help me

Answer 1

ok i think graphing would be the easiest way to do this :D
do u have geogebra app?

Answer 2

@blahhedup101 u there?

Answer 3

yeah im here

Answer 4

@Godlovesme

Answer 5

and no i dont have a graphing app

Answer 6

hmm is it fine if i graph it and u determine how many solutions the line will have? solution is just the intersection so it's easy :)

Answer 7

ok sounds good :)

Answer 8

great! :D
so first are u familliar with the slope-intercept formula?

Answer 9

y= mx + b ?

Answer 10

sorry my mom was talking to me

Answer 11

but yes i am familiar with y=mx+b

Answer 12

it's cool :)
so i guess you know that m stands for slope and b represents the y-intercept

Answer 13

yes

Answer 14

awesome! so if two lines have the same slope, it means thy are parallel. And if two lines are parallel, they will NEVER intersect which means there will be no solution
so do u see any lines with the same slope?

Answer 15

oh ok that makes sense and idk i dont know how to graph them

Answer 16

no we dont need to graph it if we find any two equations that have the same slope
for example y= 3x +1 and y= 3x +2 have the same slope,3 so the lines are parallel so there is no solution ( they will never intersect)
make sense?

Answer 17

ohhhhhhhhh

Answer 18

ok ummm

Answer 19

what about the last on is that no solution?

Answer 20

so if u look at the first pair, you can tell that they have the same slope because -x is the same thing as -1x

Answer 21

and the second last one is no solution

Answer 22

hold on we're on the first one

Answer 23

y= -x -2
y= -x -6
do this equations have the same slope? ^^

Answer 24

um no

Answer 25

um actually they do, look -x means -1x so we will have
y= -1x -2
y= -1x -6
they both have a slope of -1

Answer 26

ohhh... i thought they didnt because of the 2 and the 6

Answer 27

that's the y-intercept , the slope is the one with x :)

Answer 28

i dont get these they are very confusing sooo the numbers dont count ?

Answer 29

sorry about the confusion :/
butt here
y=mx+b
we will be given numbers for m and b like
y= 2x + 3
m = slope
b= y-intercept
so in this case our slope is 2 and the y-intercept is 3
got it?
