If the line is tangent to circle at point A and the radius ( suppose AO) has a slope of 2.5 then a slope of the tangent line is :
Explanation: The product of slopes of two perpendicular lines is -1. To get second slope we have to divide -1 by the first one.
Answer:
C) - 0.4
Answer:
-1/6
Step-by-step explanation:
Slope=change in y/change in x
Y-values: 8 and -4
X-values: 4 and 2
Change is the difference in position (subtract)
8- (-4)/(4-2)=12/2=6 = first slope
Perpendicular lines have opposite reciprocal slope
Answer:
which is none of your choices....
Did you mean (8,-3) and (4,-7)?
Step-by-step explanation:
We need to first find the distance between the x's.
Then the distance between the y's.
The distance between the x's is 8-4=4.
The distance between the y's is -3-(-7)=4.
So the distance between two points is .
So we already found x1-x2 and y1-y2 so now we have:
Multiply both sides by -5/3.
X= 6 times -5/3
X= -10
