A linear equation is graphed. Which of the following equations represents the graph?

• -2x - y = 6

• x + 2y = -6

• x - 2y = 6

• 2x + y = 6

The conversion of degrees Celsius to degrees Fahrenheit can be represented by a linear relationship. The table shows the linear relationship between y, the temperature in degrees Fahrenheit, and x, the temperature in degrees Celsius from the freezing point of water.

Write an equation in point slope for point (20, 68) that best represents f, the temperature in Fahrenheit, when the temperature is in c , Celsius?
