Below, you are given the 2012 value of a product and the rate at which the value is expected to change during the next 5 years. Use this information to write a linear equation that gives the dollar value V of the product in terms of the year. (Let t = 12 represent 2012.) 2012 Value Rate $44,000 $2600 decrease per year STEP 1: Find the point on the line that corresponds to the information given above. (t, V) = STEP 2: Find the slope of the line. STEP 3: Use the point-slope formula to find the equation of the line. V - ________ = __________ (t - ____________)
Equations and Inequations
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.
