attashe74 [19]

Answer:

y = 700x - 400

Step-by-step explanation:

A negative number represents an altitude below sea level.

Beginning: -400

y = mx + b

y = mx - 400

In 2 hours the altitude was now 1000 m.

1000 m - (400 m) = 1400 m

The altitude went up 1400 m in 2 hours. The rate of change is

1400/2 m/h = 700 m/h

The rate of change is the slope.

y = 700x - 400

The area of a room is 26.025 m sqaure. If its length is 12.5m . find the breadth of the room

ddd [48]

Answer:

2.082.

Step-by-step explanation:

Solution,

Given,

Area ( A ) = 26.025 m².

Length ( L ) = 12.5 m.

Now,

Breadth ( B ) = Area ÷ Length.

= 26.025 ÷ 12.5

= 2.082.

Thus, The breadth of the room is 2.082 m.

What is the equation of the line shown below?

hoa [83]

Answer:

The equation of line in SLOPE INTERCEPT is y = x -1

Step-by-step explanation:

Here, two points given on the line equation are

A(5,4) and B(-4,-5)

Now The slope of the line AB = $m = \frac{y_2 - y_1}{x_2 - x_1}$

or, $m = \frac{-5 -4}{-4 -5} = \frac{-9}{-9} = 1$

⇒ the slope of AB is m = 1

By SLOPE INTERCEPT FORMULA:

The equation of a line with slope m and a point (x0, y0) is given as

(y-y0)= m (x-x0)

⇒ The equation of line with point (5,4) is:

(y - 4) = (1) (x -5)

or, y - 4 = x - 5

⇒ y = x - 5 + 4

Now, SLOPE INTERCEPT FORM of a line equation is y = mx + c

⇒ y = x -1

Hence, the equation of line in SLOPE INTERCEPT is y = x -1
