Question 6
Determine the equation of the linear function with the function values given below.
Enter the correct value for each sign and constant as indicated.
  • Press each hotspot.
  • Label the corresponding number with "+" or "-" to complete the blanks that ore shaped like circles.
  • Label the corresponding number with a constant to complete the blanks shaped like rectangles. The constants should be integers or rational numbers in simplified fraction form. Examples: 1 /2,- 2 /3, etc.)
Steps
1. First, find the slape (m) by using the formula
2. Next, use the slope-intercept form y = mx + b and substitute one of the points given (2,-12) or (5,-3) in for x and y and the slope you found for m. Solve for b.
3. Rewrite the y = mx + b with the slope you found (m) and the y intercept (b)
 
f(2) = -12 and f(5)=-3
     f(x) =  ?x  ?   ?

Question 2
y varies directly with x, and y = 21 when x = 24. What is the constant of variation for their relationship?
Hint: Because you know X and Y vary directly, their relationship is defined by the equation y=k x_{\text {or }} k=\frac{y}{x}
Use the equation and substitute 21 in place of y and 24 in place of x.
 
 
 
What is the equation that represents the direct variation between Y and X?
Plug in the value of k into the equation y = kx
 
 
 
 
Question 3
If x and y vary directly and y=12 when x=3, what is the constant of variation for their relationship?
 
Hint: Because you know x and y vary directly, their relationship is defined by the equation or  
Use the equation   and substitute 12 in place of y and 3 in place of x.  
 
 
A  
B  
C   
 
Question 4
In the previous practice problem, you found that if x and y vary directly and y=12 when x=3, the constant of variation for the relationship is 4 .
What is the value of y when x=6
The equation y=4 x models the relationship between x and y for this scenario. Substitute 6 in place of x.
