State whether each function is a linear function. Write yes or no and explain your answer.

Ex 4) The linear function can be used to find the number of degrees Fahrenheit f (C) that are equivalent to a given number of degree Celsius C. On the Celsius scale, normal body temperature is 37°C. What is it in degrees Fahrenheit?

STANDARD FORM of a LINEAR EQUATION  Write each equation in standard form. Identify A, B, and C.

Y-INTERCEPT  X-INTERCEPT  The point of intersection of the line and the y axis. (x=0) The point of intersection of the line and the x axis. (y=0) Find the x-intercept and the y-intercept of the graph of the linear equation. Then graph the equation.
