Answer:

y + 4 = - (x - 5)

Step-by-step explanation:

The equation of a line in slope- intercept form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 1 and (a, b) = (5, - 4) , then

y - (- 4) = - 1 (x - 5) , that is

y + 4 = - (x - 5)

Answer:

y+4=-(x-5)

Step-by-step explanation:

Point-slope form equation is written as:

y-y_1=m(x-x_1)

where m is the slope and (x_1,y_1) is the point which the line passes through  so to to find the equation of line which passes through the point

(5 , -4) it means the point should satisfy the equation which furthermore means that the point lies on the lie so we can replace y1 with -4 and x1 with 5 and since we have m = -1 we can thus find b and rewrite the equation like this:

y-y_1=m(x-x1)\\y-(-4)=-1(x-5)\\y+4=-x+5

since we need it point-slope form we leave it like this

y+4=-(x-5)

Find the length of JL<br> 15<br> None of the other answers are correct<br> 12<br> 3
r-ruslan [8.4K]

Answer:

D: 12

Step-by-step explanation:

The entire segment KI is composed of the segments KJ and JI. So:

KI=KJ+JI

We know that KI is 15.

KJ is (2x-15) and JI is (2x-6). Substitute:

15=(2x-15)+(2x-6)

Solve for x. Combine like terms:

15=4x-21

Add 21 to both sides:

4x=36

Hence, the value of x is:

x=9

We know that JI is 2x-6.

We will substitute 9 for x to find JI. So:

JI=2(9)-6=18-6=12

Hence, our answer is D.
