Write the word or phrase that best completes each statement or answers the question. Graph the linear function by plotting the x and y intercepts. 1) 6x 12y 12 = x105 5 10 y 10 5510 x105 5 10 y 10 5510 Graph the line. 2) y = 4x 3 x8642 2 4 6 8 y 8 6 4 22468 x8642 2 4 6 8 y 8 6 4 22468 3) x 4y =  4 x105 5 10 y 10 5510 x105 5 10 y 10 5510 Determine the slope of the line from the given graph. 4) x105 5 10 y 10 5510 x105 5 10 y 10 5510 5) x105 5 10 y 10 5510 x105 5 10 y 10 5510 Graph a line that contains the given point and has the given slope. 6) (8, 8), 2 3 = m x10 10 y 1010 x10 10 y 1010 1 Find the slope of the line that goes through the pair of points. 7) ( 3, 8) and (6, 8) 8) (5, 8) and (5, 4) 9) ( 6, 9) and (3, 4) Use the given conditions to write an equation for the line in slope intercept form. 10) Slope = 3 4 , passing through (5, 5) 11) Slope = 2 7 , y intercept = 2 12) Passing through (8, 4) and (3, 7) Write an equation in slope intercept form for the line described. 13) Passes through (2, 2) with slope 3 4 14) Passes through ( 3, 6) and is parallel to the line 3x + 7y = 30 15) Passes through (5, 7) and perpendicular to the line 8x + 9y =  23 Use the given conditions to write an equation for the line in point slope form. 16) Passing through ( 4, 2) and ( 2, 8) Find an equation of the line with the given slope that passes through the given point. Write the equation in the form Ax + By = C. 17) m = 3; (4, 9) Find an equation of the line passing through each pair of points. Write the equation in the form Ax + By = C. 18) ( 5, 2) and (2, 10) Solve. 19) An investment is worth $3596 in 1993. By 1998 it has grown to $4511. Let y be the value of the investment in the year x, where x = represents 1993. Write a linear equation that models the value of the investment in the year x....
