 Linear-equations/732039: Consider the line 3x+8y=5 What is the slope of a line parallel to this line? What is the slope of a line perpendicular to this line? I am so confused Tiff1 solutions Answer 447452 by Alan3354(30968)   on 2013-03-30 14:19:05 (Show Source): You can put this solution on YOUR website! Consider the line 3x+8y=5 What is the slope of a line parallel to this line? What is the slope of a line perpendicular to this line? -------------- Put 3x+8y=5 into slope-intercept form. That means solve for y. -------- 3x+8y=5 y = (-3/8)x + 5/8 ---- The slope is -3/8 All parallel lines have the same slope, -3/8 --------- The slope of lines perpendicular is the negative inverse, = +8/3 ------ That's all there is to that.
 Expressions-with-variables/732037: I need help understanding how to solve x-6y= -51, 3x-7y= -54 using the substitution method. Algebra confuses me immensely. Do I solve for x first, or y first?1 solutions Answer 447449 by Alan3354(30968)   on 2013-03-30 14:16:08 (Show Source): You can put this solution on YOUR website!I need help understanding how to solve x-6y= -51, 3x-7y= -54 using the substitution method. Algebra confuses me immensely. Do I solve for x first, or y first? ---------------- You can solve for either first. Pick the one that's easiest. x-6y= -51 --> x = 6y - 51 Solving for y would cause fractions. ---------- Sub for x in 3x-7y= -54 3(6y-51) - 7y = -54 18y - 153 - 7y = -54 11y = 99 y = 9 ========================== Sub for y into any equation to find x. x-6y= -51 x - 6*9 = -51 x = 3 That's it.
