Complete each ordered pair so that it is a solution of the given linear equation. Use the graph of f below to find f(1). f(1) = x - 2y =4; ( , 1), (-2, ) The first ordered pair is (1) . The second ordered pair is ( -2.) 2 1 1 2 8 4 8 8 + 8 8 10 " 2 Find the slope-intercept equation of the line that has the given characteristics. Identify any x-intercepts and y-intercepts in the graph to the right. Identify the x-intercept(s). Slope - 6 and y-intercept (0,6) O A. The x-intercept(s) is/are (Type ordered pairs, using integers or fractions. Use a comma to separate answers as needed.) The equation is y =. O B. There are no x-intercepts. 2 4 6 8 10 10 -8 6 22 7 (Simplify your answer. Type your answer in slope-intercept form.) Identify the y-intercept(s) . O A. The y-intercept(s) is/are (Type ordered pairs, using integers or fractions. Use a comma to answers as needed.) O B. There are no y-intercepts In 2001 there were 6680 electric-powered vehicles in use in the United States. In 1998 only 4760 electric vehicles were being used. (Source: U.S. Energy Information Administration) a. Assume that the relationship between time, x, and number of electric-powered vehicles, y, is linear. Write an equation in slope-intercept form describing this relationship. Use ordered pairs of the form (years past 1998, number of vehicles). The equation is . (Type your answer in slope-intercept form.) b. Use this equation to predict the number of electric-powered vehicles in use in 2009. vehicles
