a)What is the value of y?   y= 6

b)The value of RS is 57 and ST is 16.

a) How is the value of y calculated?

From the number line,

RS = 9y +3

ST= 2y + 4

RT = 73

Rewriting as equation,

RT = RS + ST

73 = 9y +3 + 2y + 4

73 = 11y  + 7

11 y = 73 - 7

11y = 66

y = 66/11

y = 6

b) What is the value of RS and ST ?

Considering the equation,

RS = 9y + 3

     =9(6) +3

     =54 +3

RS = 57

Considering the equation,

ST = 2y + 4

     =2(6) +4

     = 12 +4

ST = 16

What is an equation?

  • An equation is a mathematical statement that demonstrates the equality of two mathematical expressions.
  • More than one variable may be present in a linear equation.
  • An equation is said to be linear if the maximum power of the variable is consistently 1.
  • Another name for linear equation is a one-degree equation.

Line L has an undefined slope. Line M is perpendicular to line L. Which of the following could be the equation of line M?
Marat540 [252]
"Line L has an undefined slope" so line L is any vertical line. 

Anything perpendicular to this vertical line will be horizontal. So line M is horizontal. 

Horizontal lines are of the form y = k for some fixed number k. The only thing that fits is choice B) y = 7 where k = 7 in this case.

Choice A graphs out a diagonal line, choice C graphs a vertical line, while choice D graphs out a hyperbola. These facts are why we can eliminate these non-answers. 

Answer: Choice B) y = 7
