504-2 Writing Equations in Slope-Intercept Form
The estimated attendance for 2020 is 4.4 million.
In 1904, a dictionary cost 30 . Since then the cost of a dictionary has risen an average of 6 per year.
Write a linear equation to find the cost C of a dictionary y years after 2004.
If this trend continues, what will the cost of a dictionary be in 2020?
a. Let y be the number of years since 1904. The C-intercept is 30, because that was the cost of a dictionary in the y
= 0 year, 1904. The slope is 6 as it represents the rate of increase in price. Write the equation in slope-intercept form
with y as x and C as y.
The cost of a dictionary after y years can be represented by the linear equation C = 30 + 6y.
b. The year 2020 occurs 116 years after 1904, so solve for C when y = 116.
So, if the trend continues, the cost of a dictionary in 2020 will be 726 , or $7.26.
Write an equation of the line that passes through the given point and has the given slope.
