A tangent line is always perpendicular to the radius that shares the point of tangency. In other words, where your tangent line touches the circle (at only one point), that line is perpendicular to the radius at that point.
Answer:
the area is 6.5
Step-by-step explanation:
Answer:
y + 1 = 8/9(x +4)
Step-by-step explanation:
Find the slope: [7- (-1)]/ [5 - (-4)] = 8/9
Using (-4, -1)
y-(-1) = 8/9[x- (-4)]
y + 1 = 8/9(x +4)
Answer:

Step-by-step explanation:
Given that the current average property value is two-sevenths more than last year’s average value.
Let x be the last year's average property
Then we have as per the given information this year property value
=
Equate this to

Answer:
y+1=9(x+3)
Step-by-step explanation:
Since the equation for point slope form is y-y₁=m(x-x₁)
enter the given points (-3,-1)
y-(-1)=9(x-(-3))
y+1=9(x+3) <-- point slope form
