How do you find the slope and intercept of #y = -3x#?

Answer 1

See a solution process below:

This equation is in slope intercept form. It just is hidden a little bit. 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 = color(red)(-3)x + color(blue)(0)#

Therefore:

The slope is: #color(red)(m = -3)#

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

Slope (m) = coefficient of x = -3 Y-intercept (b) = There is no y-intercept because the equation is in the form y = mx, indicating a line passing through the origin (0,0).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
