KL = 23

so you just have to add both of the segment lengths together.

each individual equation is already given in the image, so I'll substitute it out below:

JK + <u>KL</u> = JL

4x+2 +<u>4x+3</u> = 45

8x + 5 = 45

8x = 40

x = 5

BUT WE'RE NOT DONE. plug in 40 for the variable X:

KL = 4(5) + 3

KL = 20 + 3

KL = 23

now i'll check my answer really quickly:

23 + 4(5) + 2 = JL

23 + 20 + 2 = JL

23 + 22 =

45

therefore, KL is 23

Anvisha [2.4K]

Answer:

y=(1/2)x+4

Step-by-step explanation:

you have 2 points but in order to find slope intercept you need slope so,

(y2-y1)/(x2-x1)

(-1+4)/(8-2)=1/2 =slope

slope intercept:

y-y1=m(x-x1)

y-2=(1/2)(x+4)

y-2=(1/2)x+2

y=(1/2)x+4
