14. Determine the slope and the y-intercept for these lines. Use graph paper and graph the lines. a. y=-2x-3 c. 5x-3y=15 b. 2x+3y=3 d. -x-3y=9 changthe 15. Determine if the two given lines parallel, perpendicular or neither. Do not graph the equations. Use Slope Intercept form. 2 a. y=x+7 and y=-x-1 3 x-1 c. y=x-1 and 6x-8y=-8 3 b. 5x-2y=6 and -10x+4y=5 d. y= and 5x+y=9 y=mth If the slope are somethe. linesone parelle 16. Use the Point-Slope form (y-y, = mx-x,)) to write the equations of the lines. Write your answer in Slope Intercept form (y = mx + b). a. The line that passes through (4,-1) and (-2,5) b. The line that passes through (-6,1) and is perpendicular to the line whose equation is x+3y=9. c. The line that passes through (2,-4) and is perpendicular to a line with a slope of -2. d. The line that passes through (-3,1) and is parallel to the line whose equation is y = -2x+4. 17.
