The equation of the line that passes through the points (-2,0) and (0,2) can be expressed in the form y=mx+b. What is the value

liq [111]

----------------------------------------------------------------
Find Slope:
----------------------------------------------------------------
$\text {Slope = } \dfrac{2 - 0}{0-(-2)}$

$\text {Slope = } 1$

----------------------------------------------------------------
Substitute Slope = 1 into y = mx + b:
----------------------------------------------------------------
y = x + b

----------------------------------------------------------------
Find y-intercept:
----------------------------------------------------------------
At point (0, 2),

2 = 0 + b
b = 2

----------------------------------------------------------------
Substitute b = 2 into y = x + b:
----------------------------------------------------------------
y = x + 2

----------------------------------------------------------------
Expressed in the form of y = mx + b:
----------------------------------------------------------------
y = x + 2

soldier1979 [14.2K]

The polynomial (a + b)(a² – ab + b²) is reconstructed as (2x + y)(4y² – 2xy + y²), then the correct option is C.

<h3>What is polynomial?</h3>

Polynomial is an algebraic expression that consists of variables and coefficients. Variables are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Tomas learned that the product of the polynomials (a + b)(a² – ab + b²) was a special pattern that would result in a sum of cubes, a³ + b³.

His teacher put four products on the board and asked the class to identify which product would result in a sum of cubes if a = 2x and b = y.

Then the polynomial equation will be

(2x + y)(4y² – 2xy + y²)

More about the polynomial link is given below.

Hi I also need help with this please and thank you

OverLord2011 [107]

Answer:

Step-by-step explanation:

y=mx+b where m=slope and b=y intercept

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

m=(-2-4)/(2+1)

m=-2 so far we have the slope

y=-2x+b, using point (2,-2) we can solve for b, the y intercept

-2=-2(2)+b

-2=-4+b

2=b so we have our line

y=-2x+2, slope is -2 and y intercept is 2

How did you identify the line of sight, angle of elevation and angle of depression?

Arturiano [62]

Answer:

The term angle of elevation denotes the angle from the horizontal upward to an object. An observer's line of sight would be above the horizontal. The term angle of depression denotes the angle from the horizontal downward to an object. An observer's line of sight would be below the horizontal.
