4y= -3x + 12 y = -3/4x + 3 The perpendicular slope is 4/3
3x-4y-6 = 0
y = -4x
The slope is -4
If: -4x+3y = 1 Then: 3y = 4x+1 And: y = 4/3x+1/3 which is now in slope-intercept form
4x + y + c = 0 or, for a line going through a given point (xo, yo): y + 4x - (xo + yo) = 0 The gradient of a line multiplied by the gradient of a line perpendicular to it is -1; or in other words: The gradient of the perpendicular line is the negative reciprocal of the gradient of the line. Thus: 2x - 8y + 23 = 0 ⇒ 8y = 2x + 23 ⇒ y = 1/4x + 23/8 ⇒ gradient of perpendicular line is -1 ÷ 1/4 = -4 Thus the equation of the perpendicular line to 2x - 8y + 23 = 0 is 4x + y + c = 0. To find the line through point (xo, yo) perpendicular to 2x - 8y + 23 = 0, use the format: y - yo = m(x - xo) ⇒ y - yo = -4(x - xo) ⇒ y + 4x - (xo + yo) = 0
4x+2y = 6 2y = -4x+6 y = -2x+3 Perpendicular slope is 1/2
-- The slope of the graph of [ 4x + y = 2 ] is -4.-- The slopes of perpendicular lines are negative reciprocals.-- The slope of any line perpendicular to [ 4x + y = 2 ] is 1/4 .
45
It is: minus 1.25
If you mean y = -4x+3 then the gradient of the line is -4 and the y intercept is 3
4x+5y = 7 5y = -4x+7 y = -4/5x+7/5 in slope intercept form So the slope of the perpendicular line is plus 5/4
If you mean: y = 4x+2 then the line perpendicular to it will have a slope of -1/4
If you mean: y = 4x+5 then the perpendicular slope is -1/4
4y= -3x + 12 y = -3/4x + 3 The perpendicular slope is 4/3
y equals 4x+1 is a parallel line to y equals 4x.
Parallel. They both have a slope of 4.
