How do you write the equation in point slope form given (4,1) , m=undefined?

Answer 1

Hazel Anglin

#y-1=(4-c)/(1-d)(x-4)#

make another point #(c,d)# and the slope can be written as #m=(4-c)/(1-d)# so #y-1=(4-c)/(1-d)(x-4)#

To write the equation in point-slope form given the point ((4,1)) and (m = \text{undefined}), use the formula (y - y_1 = m(x - x_1)), where ((x_1, y_1)) is the given point and (m) is the slope. Since the slope is undefined, the equation will be in the form (x = a), where (a) is the x-coordinate of the given point. Thus, the equation in point-slope form is (x = 4).

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.
