Answer 1

There is an easy way to figure these things out

Answer 2

how

Answer 3

Figuring out where the line crosses the x and y axis,

Answer 4

sorry if i don't reply right after

Answer 5

A

Answer 6

so to determine a line, you need 2 points on the line.

Answer 7

idk, i havent looked at any of the graphs, i am telling you how to go about it

Answer 8

ok I am going to have to work on History too so I don't want to be mad if i don't reply right away

Answer 9

To find where the line crosses the Y-Axis, we can set X=0, and find Y

y + 1 = (3/5)(x - 3) Letting X=0

Y + 1 = (3/5) ( 0 - 3)

Y + 1 = -9/5

Y = -9/5 - 5/5

Y = -14/5

So when we let X=0 we found Y is -14/5, or about -2.8

The point x=0 , y=-2.8 is where the line crosses the Y-axis

Answer 10

Actually, that is enough information to decide which answer it is,

Answer 11

Which one crosses the Y-axis at -2.8

Answer 12

C

Answer 13

yep, none of the other lines do, so we dont need to find any other information

Answer 14

thanks

Answer 15

you're welcome
