Weegy: The required equation is y = x -4 Solution: 1 x -1 y = 4 Find the slope of this line make y the subject -1 y = - x + 4 Divide by -1 y = x -4 [ ] User: Find the missing coordinate. (-3, ) is a solution of y=4-3x? Weegy: y=4-3x y=4-3*-3 y=4+9 y=13 (-3,13) (-3, ) y = 4 - 3x Substitute -3 in for x, [ to find y. y = 4 - 3(-3) {substituted -3 in for x} y = 4 + 9 {multiplied -3 by -3} y = 13 {added 4 and 9} ] User: A line "k" passes through points (4,2) and (-4,4). A second line "h" passes through the points (-8,1) and (8,-3). Is line "k" parallel to line "h"? Why or why not? Weegy: No its not parallel to the line h. User: Write each equation in slope-intercept form. The identify the slope and the y-intercept for each line. 2x-y=12? Weegy: 2x-y=12, slope: 2, y-intercept: -12. User: Find an equation of the line that passes through the given point and has the given slope. Express your answer in slope-intercept form. (8,0), m=-3 Weegy: y=-(3/5)x-12 User: Without graphing, determine whether the following pairs of lines are parallel, perpendicular, or neither? 5x-6y=19 and 6x+5y=-30 Weegy: slope of both lines are 6/5 and -5/6, which means these slopes are negative reciprocals, so the lines through the points are (b) perpendicular. User: Explain when to use a solid line as a boundary when graphing a linear inequality. Weegy: When the inequality is "greater than or equal to", or "less than or equal to", you can use solid lines. When the inequality is "greater than" or "less than", use dashed lines. (More)
