How do you find the x and y-intercept given #y = 4x#?

Answer 1

y-intercept #=0#
x-intercept #= 0#

Given #y = 4x#

The y-intercept is the value of #y# when #x=0# #color(white)("XXXX")##y = 4(0)##color(white)("XXXX")##rarr##color(white)("XXXX")##y=0#

The x-intercept is the value of #x# when #y=0# #color(white)("XXXX")##(0) = 4x##color(white)("XXXX")##rarr##color(white)("XXXX")##x=0#

To find the x-intercept, set y equal to zero and solve for x. To find the y-intercept, set x equal to zero and solve for y. For the equation y = 4x, the x-intercept is (0, 0) and the y-intercept is (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.
