Write an equation for (4,6) and (-4,0)

1 answer:

6 0

Not an equation for those 2 points, but rather "the equation of the line thru (4,6) and (-4,0).

6 - 0
Slope? m = ----------- = 6/8 = 3/4
4 -(-4)

Equation? Start with y = mx + b. Then 6 = (3/4)(4) + b, or 6 = 3 + b. b = 3.

The desired equation is y = (3/4)x + 3.

Find the measure of AC.

alexira [117]

Answer:

AC = 23 so it be D

Step-by-step explanation:

plug AC = DF ---> 21x-19 = 3x+17

sub. 3x by both sides --> 18x-19 = 17

add 19 to both sides --> 18x = 36

divide both sides by 18, x = 2

plug x back into 21x-19 to find AC

21(2) - 19

42 - 19 = 23

It is centered at (h,k) --> (0,0) and has a radius 9

The equation of the circle is

$(x-h)^{2} +(y-k)^{2} =r^{2} \\(x-0)^{2} +(y-0)^{2} =r^{2}\\x^{2} +y^{2} = 9^{2}$

Hope that helps!
