Question

What is the slope and y-intercept of this line `f(x)= -8x - 7`?

Answer 1

The slope-intercept form of a linear equation is: `f(x) = color(red)(m)x + color(blue)(b)`

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

For this equation `f(x) = color(red)(-8)x + color(blue)(- 7)`

The slope is `color(red)(m = -8)`

The y-intercept is `color(blue)(b = -7)` or (0, `color(blue)(-7)`)
