Question

3x-y=0
2x-y=1
i am trying to solve these equations by graphing
do you solve each equation first by putting it y=mx+b format

Answer 1

suggestion,
add y to both sides

Answer 2

2x-y=1
2x-y+y=1+y
2x=1+y

no we want to get rid of the 1 by subtracting 1 to both sides
2x-1=1-1+y
2x-1=y

y=2x-1

that general process

Answer 3

I don't understand how you would graph these equations

Answer 4

the slope is m
the y intercept is b

y intercept means the point (0,b)

slope is rise over run

Answer 5

I am so confused on this graphing part how do you get the answer to know how to graph them

Answer 6

the answer would be the point of intersection

Answer 7

i understand that but i don't understand how get the answer to graph them

Answer 8

did you graph them yet?

Answer 9

no because I don't understand how to

Answer 10

do you know what a coordinate point is?

Answer 11

no

Answer 12

oy... thats a problem

Answer 13

coordinate points come in the form of (x, y)

Answer 14

oh okay I know what you mean now

Answer 15

teh easiest method to graph, cause i dont wnat to explain slope

make a t chart



solve for y given a specific x, then plot the point

then use a ruler to connect the point with a single line

Answer 16

so the equation would
3x-y=0
3x-y+y=0
3x=0+y
so my point would be 3,0 for the first equation

Answer 17

no

substitute for x, then solve for y
if x =0, y=0
if x =1, y =3
if x=-1, y=-3

Answer 18

in this case, b=0, b is the y intercept
the y intercept comes in the form of (0,b)
the y interecept is (0,0)

Answer 19

slope means, from point to point, you go up 3 units and over 1
