What is the slope of a line that is perpendicular to the line represented by the equation 3x plus 4y equals 12?
4/3
First, get this into slope-intercept form (get y by itself).
3x+4y=12 -> Move 3x to the right by subtracting from both sides.
-3x -3x
4y=12-3x -> get y alone by dividing everything by 4.
4y=-3x+12
÷4 ÷4 ÷4
y=(-3/4)x+3 -> The slope is -3/4.
To get the perpendicular line's slope you take the slope (-3/4) and flip it and switch the sign: negative becomes positive, 3/4 becomes 4/3.

What is the equation of the line passing through 3 -4 and it is perpendicular to the line 5x -2y equals 3?
Known equation: 5x -2y = 3 or y = 5/2x -3/2 Slope of equation: 5/2 Slope of perpendicular equation: -2/5 Perpendicular equation: y --4 = -2/5(x -3) => 5y = -2x -14 Perpendicular equation in its general form: 2x+5y+14 = 0
What is the equation of the line passing through the point -2 -3 and is perpendicular to the line 4x plus 3y -5 equals 0?
Perpendicular equation: 4x +3y -5 = 0 Perpendicular slope: -4/3 Slope of line: 3/4 Point of line: (-2, -3) Equation of line: y - -3=3/4(x - -2) => 4y - -12=3x - -6 => 4y = 3x -6 Therefore the equation of the line is: 4y = 3x -6 or 3x -4y -6 = 0

There is no "equals" sign therefore "x-9" is NOT an equation.
What is the slope of a line that is perpendicular to the line represented by the equation y - 3x equals 8?
y - 3x = 8 standard form is y = mx + b m = slope y = 3x + 8 in this form slope m is 3 The perpendicular line slope is the negative inverse of m -1/m = -1/3

y = x
What is the y intercept and slope in this equation x equals -5?
There is no y-intercept or slope for this given equation, because its graph is a vertical line perpendicular to the x-axis.
What is the slope of the line that is perpendicular to the line whose equation is 3X plus 2Y equals 9?
the slope will be positive 1.5x the whole equation is y=4.5+1.5x
Is y equals -3x plus 3 and 4y plus x equals -1 perpendicular lines?
No because the slope of the second equation is 1/4 and for it to be perpendicular to the first equation it should be 1/3
