The answer is 15

these chords are congruent because the radius of the circle are perpendicular to the them
so we can find EF by making an equation:
$3x + 5 = x + 35 \\ 3x - x = 35 - 5 \\ 2x = 30 \\ x = \frac{30}{2} = 15$

so EF is = 3(15)+5=50

What is the point slope of the line when slope is -4 and the given coordinates are (4,-9)

Lina20 [59]

The point-slope form of the equation of a straight line is:

$y-y_1=m(x-x_1)$

We have:

$m=-4\\(4;-9)\to x_1=4;\ y_1=-9$

Substitute:

$y-(-9)=-4(x-4)\\\\\boxed{y+9=-4(x-4)}$
