Question

help? @bibby @Data_LG2 @Directrix

Answer 1

oh hold on let me get screenshot

Answer 3

it part a basically asking why the solution is where the lines intersect?

Answer 4

pretty much, yeah

Answer 5

ok the wording is weird

Answer 6

let me put together an explanation and can you tell me if it looks ok?

Answer 7

sure

Answer 8

ok here

The x-coordinates of the points to the solution to where the equations intersect is the solution of x, because that is where the two lines meet.

i felt like i explained that weird. its awkward fr me to explain

Answer 9

how would you explain it?

Answer 10

because when you graph the two equations, you will find a coordinate at which they meet. This coordinate would have an x-coordinate and a y-coordinate which is your solution

Answer 11

I've never really had to explain it until I read that question.
as I understand it, when you set 2 equations equal to each other, you're finding the x coordinate where they have an equal y

for example, y=2x+6, y=6x-2

2x+6=6x-2
2x+8=6x
8=4x
x=2

Answer 12

where they share a y*

Answer 13

so when we solve that equation, we've solved the x value of the intersection point

Answer 14

got it

Answer 15

i got part b and c done

Answer 16

do you want me to give you one last run through on your answer for part a

Answer 17

sure

Answer 18

did you rewrite it at all?

Answer 19

yes sorry for late response
