Question

What is the slope of `y=-7x+9`?

Answer 1

The slope is `color(red)(-7)`

Explanation:

We can obtain the slope directly from this equation which is already in 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.

For the equation in this problem:

`y = color(red)(-7)x + color(blue)(9)`

So the slope is `color(red)(m = -7)`
