Answer 2

Answer 3

if x = 0, then what is the value of y?

Answer 4

0 + 3y = 6
y = 2

Answer 5

so (0,2) is one point on the graph

Answer 6

if y = 0, then x = ??

Answer 7

x = 3

Answer 8

(3,0) is the second point

you need just 2 points to graph a linear equation

Answer 9

I mean I need help using it "algebraically"

Answer 10

you mean solving 2x + 3y = 6 for y?

Answer 11

2x + 3y = 6
2x - 2x + 3y = 6 - 2x
3y = 6 - 2x

Answer 12

But I am having confusions solving it from there.

Answer 13

to isolate y in 3y = 6-2x, divide both sides by 3

Answer 14

So it would be
y = 2 - 2/3x ?

Answer 15

yes \[\Large y = -\frac{2}{3}x + 2\]

Answer 16

Why did you switch it ?

Answer 17

Like is it necessary to do that?

Answer 18

I placed it into y = mx+b form

Answer 19

no it's not mandatory
