Question

How do i find the coordinates of x + 3y = 9 ?

Answer 1

coordinates of what?

Answer 2

For a graph

Answer 3

solve for y it will give you slope intercept form then plot

Answer 4

Whats x?

Answer 5

9

Answer 6

ok, let me explain.

x+3y = 9

// subtract x from both sides to remove the x from the left side of the equation.
3y = 9-x

// divide both sides by 3
y = 3-1/3(x)

// move the x left on the right side of the equal sign.
y = (-1/3)x+3
