Question

X+3y=0. Solve for y, then graph the equation

Answer 1

Explanation:

Subtract x on both sides

`3y=-x`

Divide both sides by 3

`y=-(1)/(3) x`

To find the y-intercept, let x = 0

y = 0, therefore the function crosses the y-axis at the origin.

To find the x-intercept, let y = 0

x = 0, therefore the function crosses the x-axis at the origin too.

The slope of the function is -1/3, from the origin, go down 1 and right 3
