What are the intercepts of #-17y-21x=8#?

Answer 1

Intercepts of -17y - 21x = 8.

To find y intercept, make x = 0 --> #-17y = 8# --> #y = - 8/17 # To find x intercept, make y = 0 --># -21x = 8# --> #x = - 8/21#

To find the intercepts of the equation ( -17y - 21x = 8 ), we set ( x = 0 ) to find the y-intercept and ( y = 0 ) to find the x-intercept.

For the y-intercept, when ( x = 0 ), we have ( -17y = 8 ), so ( y = -\frac{8}{17} ).

For the x-intercept, when ( y = 0 ), we have ( -21x = 8 ), so ( x = -\frac{8}{21} ).

Therefore, the y-intercept is ((-17, -\frac{8}{17})) and the x-intercept is ((-\frac{8}{21}, 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.
