Imagine we drew a line from the centre (2,0) to the point (0,4).
Essentially the line<u> we drew from the centre to that point on the circle is perpendicular to the tangent line slope-wise</u>.
The <u>slope of that line from the centre to the point is -2</u> based on the slope's equation or formula.
slope = 
Therefore the <u>tangent equation's slope is 1/2</u> since any perpendicular line's slope is the negative reciprocal of the original line's slope.
By<u> using the point-slope form, we must have the point on the tangent plane (0,4) and the slope we found which is 1/2</u>.

Hope that helps!
Answer:
2 4/7
Step-by-step explanation:
3/7+4/7= 7/7 or 1 whole
So you add that to the 5 and get 6, then you need 2 to get to 8 because 6+2=8
Hope this helped!!!
Answer:
0.1 show be the answer.
Step-by-step explanation:
1/4 * 2/5 = 0.1 = 1/10
There are two possibilities. It could be +2.125 , and it could be -2.125 .
