Across 3. Lines where the product of the slope is -1 are _______. 4. Are the lines perpendicular? m1=1/4, m2=-4 5. An equation of the form y=mx + b is in "?" form. 7. A "?" is a graph in which two sets of data are plotted as ordered pairs in a coordinate plane. 11. True or False, the change in x is over the change in y. 12. The "?" of a line is a number determined by any two points on the line. 13. b is representative of "what value" is our equations 17. If line K1 has a slope of 2/3 and K2 has a slope of 2/3, are the lines parallel? 18. If the data points do not all lie on a line, but are close to a line, you can draw a "_?_" 20. The calculator uses a statistical method to find the line that most closely approximates the data. The line is called the "_?_" 21. Slope is the ratio of the change in y (rise) to the change in x (?) 22. M is representative of "what value" is our equations? 23. As x decreases, y decreases this is called a ________ correlation.

Y= 4/5x + 10, What is the y-intercept? 9. Y = 1/2x - 21, What is the value of slope? 10. A line with a slope of 0 is a ________ line 14. As x increases, y increases this is called a ________ correlation. 15. An equation generated using the coordinates of a known point and athe slpe of the line is " ? " 16. A slope with 0 on the bottom i.e 5/0 is what? 17. What is the slope intercept form? 19. Lines that have the same slope are ________. 23. If the product of K4 and K5 are -1/2 are these lines perbendicular?
