Answer:

Step-by-step explanation:

18.

slope of line y=2x-5 is 2

slope of line ⊥ to y=2x-5 is

m=-1/2

eq. of reqd. line through (10,6) with slope -1/2 is

y-6=-1/2(x-10)

multiply by 2

2y-12=-x+10

2y+x=10+12

2y+x=22

2y=-x+22

y=-1/2x+11

19.

slope of line y=12x+5,m=12

eq. of line through (5,2) with slope 12 is

y-2=12(x-5)

y-2=12x-60

y=12x-60+2

y=12x-58

compare with y=mx+b

b=-58

Y – 11 = 3(x – 2) in standard form

emmainna [20.7K]

Answer:

3x + y = -5

General Formulas and Concepts:

Pre-Algebra

Distributive Property
Equality Properties

Algebra I

Standard Form: Ax + By = C

Point-Slope Form: y - y₁ = m(x - x₁)

x₁ - x coordinate
y₁ - y coordinate
m - slope

Step-by-step explanation:

Step 1: Define

[PS] y - 11 = 3(x - 2)

Step 2: Rewrite

Find Standard Form

Distribute 3: y - 11 = 3x - 6
Subtract 3x on both sides: -3x - y - 11 = -6
Add 11 to both sides: -3x - y = 5
Factor -1: -1(3x + y) = 5
Divide -1 on both sides: 3x + y = -5
