The value of a company is increasing at constant rate. In January 1990 the company was worth 10 million dollars and in January 2006 it was worth 66 million dollars. Let y stands for the value of the company in millions of dollars and x stands for the time in years since 1990. The relation between x and y is linear. a. Find equation of the line in slope intercept form. b. Write the unit of the slope. c. Write a sentence to explain the meaning of the slope. Use numbers and units in your explanation.

Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
