What is the x-intercept of #y=-4x+4#?

Answer 1

The linear equation form is #y=mx+c# :)

Where: #m# is the gradient of the equation and #c# is the #y#-intercept. To find the intercepts, substitute 0 into either of the #x# or #y# values.

Therefore, to find the #x#-intercept, sub 0 into the #y# value. In equation form, that is: #y=mx+c# #0=-4x+4# #4x=4# #x=1#

Therefore, the coordinates of the #x#-intercept are #(1,0)#. Hope this helps!

To find the x-intercept of the equation y = -4x + 4, set y equal to zero and solve for x. 0 = -4x + 4 4x = 4 x = 1 So, the x-intercept is (1, 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.
