Question

How do you find the slope and y-intercept of the line `y=-2x-7`?

Answer 1

See a solution process below:

Explanation:

The equation in the problem is 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.

Therefore, for this equation: `y = color(red)(-2)x - color(blue)(7)`

The Slope is: `color(red)(m = -2)`

The Y=Intercept is: `color(blue)(b = -7)` or `(0, color(blue)(-7))`
