The formula for converting Celsius temperatures into Fahrenheit temperatures is a linear equation. Water freezes at 0 degrees Celsius, or 32 degrees Fahrenheit, and it boils at a hundred degrees Celsius, or 212 degrees Fahrenheit. Find the slope and the y-intercept for a graph that gives degrees Celsius on the horizontal axis in degrees Fahrenheit on a vertical axis then write an equation in slope-intercept form that converts degrees Celsius into degrees Fahrenheit.
