Question

How do you find the slope and intercept of `y + x = 0`?

Answer 1

See the entire solution process below:

Explanation:

Solve for `y` to transform the equation to slope-intercept form. The slope-intercept form of a linear equation is: `y = color(red)(m)x + color(blue)(b)`

Where `color(red)(m)` is the slope and `color(blue)(b)` is the y-intercept value.

`y + x = 0`

`y + x - color(red)(x) = 0 - color(red)(x)`

y + 0 = -color(red)(x)#

`y = color(red)(-1)x + color(blue)(0)`

Therefore:

The slope is: `color(red)(m = -1)`

The y-ntercept is: `color(blue)(b = 0)` or `(0, 0)`
