Answer:

Segment JK is a chord in circle H

Line LM is a secant to circle H

Step-by-step explanation:

* Lets revise some definition in the circle

- The radius of the circle is a line segment drawn from the center of

the circle to a point on the circumference of the circle

- The chord of a circle is a line segment whose endpoints lie on the

circumference of the circle

- The secant is a line intersect the circle in two points

- The tangent is a line touch or intersect the circle in one point

* Now lets solve the problem

- In circle H

∵ JK is a segment in circle H

∵ Point J lies on the circumference of circle H

∵ Point K lies on the circumference of circle H

∴ Segment JK is a chord in circle H

∵ LM is a line

∵ LM intersect circle H in two points L and M

∴ Line LM is a secant to circle H

Please help me this question

Annette [7]

Step-by-step explanation:

Hey there!

The given point is (8,-3) as (x1,y1) and slope (m) = -3/4.

Note: use one point formula for finding the equation.

$(y - y1) = m(x - x1)$

Put all values.

$(y + 3) = - \frac{ 3}{4} (x - 8)$

Simplify it.

$(y + 3) = - \frac{ 3}{4} x - 8 \times - \frac{3}{4}$

$(y + 3) = - \frac{3}{4} x + 6$

$y = - \frac{3}{4} x + 6 - 3$

$y = - \frac{3}{4} x + 3$

Therefore, the equation is; y = -3/4x+3.

Hope it helps...
