Answer:
y = 20x
m = 20 and b = 0
Step-by-step explanation:
For input values of x = 1, output value of y = 20 and for x = 4, y = 80.
Therefore, the equation of this relation can be written as
[tex]\frac{y - 80}{80 - 20} = \frac{x - 4}{4 - 1}[/tex]
⇒ 3(y - 80) = 60(x - 4)
⇒ 3y - 240 = 60x - 240
⇒ y = 20x
Now, y = mx + b is the equation and hence, m = 20 and b = 0 and the actual equation is y = 20x. (Answer)
