Then write the equation of the line in slope intercept form (y=mx+b form) Slope = _______________ Y-intercept = ___________ Equation of the line: ________________ Question #2: State the slope & the y-intercept of line below. Then write the equation of the line in slope intercept form (y=mx+b form) Slope = _______________ Y-intercept = ___________ Equation of the line: ________________ Question#3: What is the slope of the line below: Question#4: What is the slope of the line below: Math8 Chapter 2 Mrs. Hallahan Page 5 Question#9: Sketch a graph of each line below. Remember you must first work to put each equation in slope intercept form. 9A) y = 2x-4 9B) 6x + 3y = 12 Question#10: Look at each equation in question 9; which is in Standard Form, and which is in Slope- Intercept form? Explain. Question#11: Write the slope intercept form of each line with the given slope and y-intercept: 11A) slope = 5, y-intercept = 0 11B) slope = 2/3 and y-intercept = 4 Math8 Chapter 2 Mrs. Hallahan Page 6 Question#12: 12A) What is always the x value of the coordinate that is the y-intercept? 12B) What is always the y value of the coordinate that is the x-intercept? 12C) If the graph of a line has the same x intercept and the same y intercept, what is that coordinate point? Question#13: Write the equation of a line, in slope intercept form, that passes through the origin, and has a slope of 1. Sketch this graph of below Math8 Chapter 2 Mrs. Hallahan Page 7 Question#14: Write the equation of the line, in slope intercept form, that is represented by the following Table of Values. Then graph on the coordinate plane below. x Y -3 -11 -2 -8 -1 -5 0 -2 1 1 2 4 3 7
