The line's y-intercept is -3 as per the information given in the table.

<h3>What is meant by slope?</h3>

The slope or gradient of a line is a numerical representation of a line's steepness and direction in mathematics. The reason for this usage is unknown, but it first appears in English in O'Brien (1844), who wrote the equation for a straight line as y = mx + b, and in Todhunter (1888), who wrote it as y = mx + c. In this case, m stands for the line's slope.

Slope is the result of calculating the ratio of vertical change to horizontal change between (any) two distinct points on a line.

We know that,

y=m x +c

From the table the points are,

A(-2,5)

B(-1,1)

C(0,-3)

D(1,-7)

Substituting the C point in the above equation we get,

-3=m(0)+c

c=-3

Consequently, the line's y-intercept is -3.

What is the missing length?
TEA [102]
Answer:  13.722 km ;  or, write as:  13  13/18 km .
___________________________________________________
Explanation:
___________________________________________________
Area = Length * width ; 
___________________________________________________
or, write as:  A = L * w ;
________________________

Given: A = 247 km² ; 
           
          L = 18 km ; 
 
          w = "y" ; 
________________________
 Find:  "y"
______________________________
  A = L * w ; 
______________________________
Plug in our values:
______________________________
  247 km² = 18 km * "y" ;  solve for "y" (in units of "km") ;

_____________________________
        18 y = 247 ; 
___________________________________________________________
Divide each side of the equation by "18"; to isolate "y" on one side of the equation; and to solve for "y" :
___________________________________________________________
        18 y / 18 = 247 / 18 ;
_____________________________________________
  to get:
_____________________________________________
              y = 13.7222222222222222...... km ;  round to: 13.722 km

                   or;  y = 13  13/18 km .

In the figure shown below, AC is parallel to DE with transversal BF
densk [106]

Answer:

<h3>X = 142°</h3><h3>Y = 38° </h3>

<em><u>Given </u></em><em><u>-</u></em><em><u> </u></em> AC is parallel to DE

angle 3y + 28 = angle X ( Vertically opposite angles are equal).

3y + 28 = X

X + Y = 180° ( supplementary angles).

3y - X = (-28)

Solving both the equation we get

multiply eq 1 with 3

3x + 3y = 540

-X + 3y = (-28)

subtracting

4x = 568

x = 142°

3y + 28 = 142

3y = 142 - 28

3y = 114

y = 38°
