Question

What is the equation of the line at the point of tangency?

A) y-1=X
B) X=3
C) y=-1
D) X+1=y

Answer 1

A horizontal line has an equation of y = a

where a is the y-coordinate of all the points on the line, it will be the same

Answer 2

I don't understand?

Answer 3

at what point on the y axis does the tangent intersect it?

Answer 4

(-1,-2) right?

Answer 5

two circles touch each other at (2,-1)
and tangent is parallel to x axis.
eq. of any line parallel to x axis is y=b where b is a real number.

Answer 6

So the answer is y=-1

Answer 7

correct :)

Answer 8

Thank you.

Answer 9
