Joanna is paid $14 per hour is this linear or nonlinear and proportional or nonporportinal

Given the statement: Joanna is paid $14 per hour.

Let x be the number of hours and y be the number of dollars paid to Joanna.

Now, writing the given situation as equation:

y = 14x

On compare with the general equation of line y= mx +b

The equation y= 14x is linear.

A proportional relationship states it is one in which two quantities vary directly with each other.

i.e, y = kx where k is constant.

Since, b = 0

so, the given equation is proportional relationship.

Therefore, the given statement is linear and proportional.

y = x + 95

y = 42 + 95

y=137 mm hg
