What is the slope of the line?

1
1/2
-2
2

Answers

Answer:

Step-by-step explanation:

The slope of the line is 2. The slope is rise over run, or change in y over change in x. So to find the slope count how much each value changes, in this graph y changes +2 and x changes +1. So the slope is 2/1 or just 2. One way to visually check the slope is to remember fraction slopes will make the line flatter and other whole numbers make the line steeper.

If P is the incenter of JKL, find each measure

Answers

Answer:

see below

Step-by-step explanation:

angle JP = (180 - 32 - 90) + (180 - 22 - 90)

= 58 + 68

= 126°

angle JKP = (360 - JMP - JLP - LNP)/2

= 360 - (180 - 32 - 90) - 126 - (180 - 22 - 90)

= 360 - 58 - 126 - 68

= 54°

MP = 7

KN = 10

JP = 11 / cos(32)

= 13

PL = 17 / cos(22)

= 18.3
