ANSWER

EXPLANATION
The diameter meets the tangent to the circle at right angles.
The sum of interior angles of a triangle is 180°.
This implies that

Group the constant terms

We simplify to obtain,

Answer:
-(3x - 1)(x - 3)
Step-by-step explanation:
-3x² + 10x - 3
-(3x² - 10x + 3)
-(3x - 1)(x - 3)
Answer:
y = -1/4x + 2.5
or
y = -1/4x + 5/2
Step-by-step explanation:
First we know that a perpendicular line is one that intersects at a 90-degree angle. This is simply the negative inverse of the slope in our case. So, 4 turns into -1/4 and that is our new slope. Next we know that we want it to pass through the point (6,1). Right now our equation is y = -1/4x + b. We can plug (6,1) into this equation and solve.
1 = -1/4(6) + b
1 = -6/4 + b
4/4 + 6/4 = 10/4
10/4 = b
simplify: 5/2 or 2.5 = b
Now we have our y-intercept, so we can complete our equation.
y = -1/4x + 2.5
or
y = -1/4x + 5/2
