Question

PLEASE HELP. solve the system by graphing.

Answer 1

@satellite73 can you help? I know its either a or b.

Answer 2

@jim_thompson5910

Answer 3

it would help by first putting both of the equations in the form, y = mx + b

Answer 4

Right, and I did that hence why I'm asking if it's a or b? because I got the graph.

Answer 5

@blurbendy

Answer 6

The graphs of a) and b) are identical

BUT

notice how the ordered pair or point listed that is the solution is different for each choice a) and b)

Answer 7

yea that's why im confused....but I really think its, a?

Answer 8

is that just a guess? It's ok if it is

Answer 9

remember every point is of the form (x,y)

so something like (7,9) means x = 7 and y = 9

you use these x and y values to figure out precisely where you are on the 2D coordinate plane. In this case, (7,9) means you start at the origin, go 7 spaces to the right, then 9 units up to land at the point (7,9)

Answer 10

SO wait, its b. right. @jim_thompson5910

Answer 11

why b?

Answer 12

because x=3

Answer 13

@jim_thompson5910

Answer 14

yes x = 3 in choice b

but look at the intersection point, is the x coordinate really 3?

Answer 15

omg this is so confusing I hate it

Answer 16

what is the x coordinate of the point of intersection

Answer 17

how many units do you have to go to the left on the x axis to get to the point of intersection?
