Which is the equation in Point-slope form of the line with a slope of 2 and passing thru the point (2,1)

Answers

Answer 1

Answer:

y - 1 = 2(x - 2)

General Formulas and Concepts:

Algebra I

Point-Slope Form: y - y₁ = m(x - x₁)

x₁ - x coordinate y₁ - y coordinate m - slope

Step-by-step explanation:

Step 1: Define

Slope m = 2

Point (2, 1)

Step 2: Write Equation

Substitute in variables:                       y - 1 = 2(x - 2)

1. All of the variables below are directly proportional, write an equation linking them:
a. V= 12 when M =4
b. T= 5 when S=1
c. Y= 34 when x=2
d. H=48 when M=4
e. P= 5 when N=10

Answers

Answer:

a. V = 3M

b. T = 5S

c. Y = 17x

d. H = 12M

e. P = 0.5N

Step-by-step explanation:

a. V= 12 when M =4

12/4 = 3, so in this case, V is 3 times M, that is, V = 3M

b. T= 5 when S=1

5/1 = 5, so in this case, T is 5 times S, that is, T = 5S

c. Y= 34 when x=2

34/2 = 17, so in this case, Y is 17 times x, that is, Y = 17x

d. H=48 when M=4

48/4 = 12, so in this case, H is 12 times M, that is, H = 12M

e. P= 5 when N=10

5/10 = 1/2 = 0.5, so in this case, P is half of N, that is, P = 0.5N

the scale on a map is 1:25000. how many km on the ground is represented by 6cm on the map?

Answers

Given:

The scale on a map is 1:25000.

To find:

How many km on the ground is represented by 6cm on the map?

Solution:

Let x be the km on the ground.

We know that,

1 km = 1000 m

1 m = 100 cm

So,

1 km = 100,000 cm

x km = 100,000x cm

The scale on a map is 1:25000. It means the ratio of map and ground is equal to 1:25000.

[tex]\dfrac{1}{25000}=\dfrac{6}{100,000x}[/tex]

[tex]\dfrac{100,000x}{25000}=6[/tex]

[tex]4x=6[/tex]

[tex]x=\dfrac{6}{4}[/tex]

[tex]x=1.5[/tex]

Therefore, 1.5 km on the ground is represented by 6cm on the map.

Answer:

x = 1

y = -2

Step-by-step explanation:

5x - 2y = 9 -----------(I)

2x + 7y = -12 --------------(II)

Multiply (I) by 7          35x - 14y = 63

Multiply (II) by 2         4x + 14y  = - 24   {Now add and thus y will be eliminated}

                                  39x         =      39

                                          x = 39/39

x = 1

Plugin x = 1 in equation(I)

5*1 - 2y = 9

5 -2y = 9

    -2y = 9 -5

    -2y = 4

        y = 4/-2

        y = -2
