Find The Equation Of The Line

Answers

Answer 1

Answer:

y = 2x - 7

Step-by-step explanation:

The question is asking for slope-intercept form, y = mx + a.

Given:

(1, -5) and (9, 11)

Find the slope (m) between the two points:

m = (y2 - y1) / (x2 - x1)

x1 = 1

x2 = 9

y1 = -5

y2 = 11

m = ( 11 - (-5) )/(9 - 1)

= 16/8

m = 2

y = 2x + a

Use one of the two points to find a (I will use (1, -5)):

-5 = 2(1) + a

-5 = 2 + a

-7 = a

a = -7

y = 2x + (-7)

y = 2x - 7

Answers

Step-by-step explanation:

from,

An = 4n -13

A1 = 4 (1) - 13

> A1 = -9

A2 = 4(2) - 13

> A2 = -5

A3 = 4(3) - 13

> A3 = -1

A4 = 4(4) - 13

> A4 = 3

(iv) The area of a rectangle with breadth
5 cm is 30 sq. cm. Find its length and
perimeter.​

Answers

Answer:

Step-by-step explanation:

if the breadth is 5cm, then you divide 30/5 to get your length since it's length times breadth to get the area, so 6cm for the length

and then it's 2b plus 2l to get your perimeter so

2(5)+2(6)=p

10 plus 12 equals p

22 is your perimeter, 6 is your length

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)

                                                     2

                  = 360 - 58 - 126 - 68

                                    2

                  = 54°

MP = 7

KN = 10

JP = 11 / cos(32)

    = 13

PL = 17 / cos(22)

    = 18.3
