How do you graph y-2=1/2 (x+6)

Mathematics
1 answer:
jeyben [28]3 years ago

The point-slope form:

y-y_1=m(x-x_1)

m - slope

(x₁, y₁) - point

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept → (0, b)

Convert the given equation to the slope-intercept form:

y-2=\dfrac{1}{2}(x+6)           <em>use distributive property a(b + c) = ab + ac</em>

y-2=\dfrac{1}{2}x+3           <em>add 2 to both sides</em>

y=\dfrac{1}{2}x+5

It is a linear function. We only need two points to plot the graph.

The first point we have from point-slope form → x₁ = -6, y₁ = 2 → (-6, 2).

The second point we have from slope-intercept form → b = 5 → (0, 5)

Find the value of the variable and DF if D is between C and F if CD 4y -9, DF 2y-7, and CF 14.
Yuri [45]
CF = CD + DF (since D is simply a point on the line, and C to that point added onto F to that point is CF), so 4y-9+2y-7=14. Adding it up, we get 6y-16=14 and adding by 16 we get 30=6y. Dividing both sides by 6, we get y=5. Plugging that into DF, we get 10-7=DF=3

The ratio of the width to the length of a rectangle is 2:3, respectively. Answer each of the following. a By what percent would
Elina [12.6K]

Answer:

The percentage increase in Area of rectangle is 200%

Step-by-step explanation:

Given as :

The  ratio of the width to the length of a rectangle is 2:3

Let The length of rectangle = 2 x

Let The width of rectangle = 3 x

∵ Area of rectangle = length × width

So, A_1 = 2 x × 3 x

Or,  A_1  =  6 x²

<u>Again</u>

The increased length of rectangle = 2 x + 2 x = 4 x

The increase width of rectangle = 3 x + 50% of 3 x

I.e The increase width of rectangle = 3 x + 1.5 x = 4.5 x

∵ Increased Area of rectangle = increased length × increased width

Or,   A_2  = 4 x × 4.5 x  = 18 x²

So, The percentage increase in area = \dfrac{A_2 - A_1}{A_1} × 100

Or, The percentage increase in area = \frac{18 x^{2}-6x^{2}}{6x^{2}} × 100

Or , The percentage increase in area = \dfrac{12}{6} × 100

∴ The percentage increase in area  = 200

Hence, The percentage increase in Area of rectangle is 200% Answer
