The line a is an illustration of a proportional linear equation, and the equation of line a is y = 1.4x
How to determine the equation of the data?
The line a passes through the following points:
(x,y) = (0,0) and (1.3, 1.82(
The above means that line a is a proportional linear equation
The constant of proportionality (k) is calculated using:
k = y/x
Using the values on the table, we have:
k = 1.82/1.3
Divide
k = 1.4
Substitute k = 1.4 in k = y/x
y/x = 1.4
Multiply both sides by 1.4
y = 1.4x
Hence, the equation of the line a is y = 1.4x
