How do you find the slope and y intercept of #y= -9x#?

Answer 1

Slope as #-9# and intercept on #y#-axis is #0#.

An equation in slope-intercept form is written as #y=mx+c#, where #m# is slope and #c# is its intercept on #y#-axis.

Hence, if one writes a linear equation as a function of #y#, one can easily get slope which is coefficient of #x# and intercept, which is constant term.

As #y=-9x# is already in this form, we have its slope as #-9# and intercept on #y#-axis is #0#, that is it passes through origin.

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.
