Answer:
Step-by-step explanation:
Equation of the line CD is given as
Slope of the line CD = -2
Slope of the line parallel to CD = -2
Equation of the line parallel to CD is given by
But this line passes through (4,5)
Substituting the values in the equation:
=>
So the overall equation of the parallel line is given by
Answer:
Step-by-step explanation:
Given
x ----- y
0.5. --- 0.8
1. --- 1.6
3.--- 4.8
25. --- 40
Required
Determine the constant of proportionality
This can be calculated using the following formula:
; Where r is the constant of proportionality;
Solve for r
When x = 0.5; y = 0.8
When x = 1; y =1.6
When x = 3; y = 4.8
When x = 25; y = 40
Notice that the value of r is constant throughout;
Hence:
