Line L passes through the points (0, --3) and (6,9).<br> (a) Find the equation of line L.
valentina_108 [34]

Step-by-step explanation:

Given points are :

(0,\:-3)=(x_1,\:y_1) \:\&\: (6,\:9)=(x_2 ,\:y_2)

Equation of line in two point form is given as:

\frac{y -y_1 }{y_1 -y_2 }  = \frac{x -x_1 }{x_1 -x_2 }  \\  \\  \therefore \frac{y -( - 3)}{ -3  -9 }  = \frac{x -0 }{0 -6 }  \\  \\  \therefore \frac{y  + 3}{ -12}  = \frac{x  }{ -6 }  \\  \\  \therefore \frac{y  + 3}{ 2}  = \frac{x  }{1}  \\  \\  \therefore  \: y + 3 = 2x \\  \\  \huge \red{ \boxed{\therefore  \: 2x - y - 3 = 0}} \\ is \: the \: required \: equation \: of \: line.

"Ten subtracted from the quotient of a number<br> and 5 is 18."
Anika [276]

Answer: n/5 - 10 = 18: this would be the equation. Your answer would be 140.

Step-by-step explanation: Let consider the number as ‘X’

Quotient of a number and 5 can be written as

                        X divided by 5

Ten subtracted from the quotient of a number and 5 can be written as

                       (X divided by 5)-10

Ten subtracted from the quotient of a number and 5 is 18 can be written as

                       (X divided by 5)-10=18

  By solving the above equation, find ‘X’

                       (X divided by 5) = 18 + 10

                    X/5=28

                       X = 28 x 5 = 140
