Question

What is the slope and y-intercept of the line `x=y`?

Answer 1

See the solution process below:

Explanation:

Rewrite the equation as:

`y = x`

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.

Putting our equation into this form gives:

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

Therefore:

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

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