Help please, i dont understand

yan [13]

Answer:

formula: y-y1 = m(x-x1)

Step-by-step explanation:

General:

1. find 2 points directly on the line and apply the formula y2-y1 over x2-x1 this answer equals m

2. then add it into the formula y-y1 = m(x-x1) remember x and y are variables so only put numbers in y1 and x1

3. solve the problem

Example:

line 1:

1. y2-y1 over x2-x1 is 4-6 over 6-4 = -1

2. y-6 = -1(x-(-4) or y-6 = -1(x+4)

3. y-6 = -1x-4

4. y = -1x-2

3. the gradient equals: y = -1x-2

Hope this helps :) Let me know if you need a better example

Use the number line below, where RS = 7y + 2, ST = 2y +6, and RT = 13y - 12

Hitman42 [59]

Answer: a. y=5

b. RS = 37 , ST =16 and RT = 53 .

Step-by-step explanation:

Given: On number line we have,

RS = 7y + 2, ST = 2y +6, and RT = 13y - 12.

a. Since its on number line so we have

RT = RS+ ST

i.e. 13y - 12 = (7y + 2) + ( 2y +6)

⇒ 13y - 12 = 7y + 2 + 2y +6

⇒ 13y-12 = 9y+8

⇒ 13y-9y = 8+ 12 [Subtract 9y from both sides and add 12 in both sides]

⇒ 4y = 20

⇒ y= 5 [Divide both sides by 4 ]

b. Now , RS = 7(5) + 2 = 35+2= 37,

ST = 2y +6 = 2 (5)+6 = 10+6 =16,

and RT = 13y - 12 = 13 (5)-12 = 65-12 = 53.

Hence, RS = 37 , ST =16 and RT = 53 .
