First, convert the equation to Slope-Intercept Form (y = mx + b) m = slope
b = y-intercept
3x - 4y = 8
Subtract 3x from both sides of the equation.
-4y = -3x + 8
Divide the entire equation by -4.
y = 3/4x -2
Now that we know that the slope is 3/4, we can convert it to its perpendicular slope. The perpendicular slope is the opposite reciprocal of the original slope. In order to find it, we flip the fraction and change the sign.
Original Slope: 3/4
Perpendicular Slope: -4/3

What would x and y be if the equation is 3x-4y equals 10 and -3x equals 4y equals 8?
3x - 4y = 10-3x - 4y = 8 -> add line 1 to line 2 3x - 4y = 100x - 8y = 18 -> -8y = 18 -> y = -18/8 = -9/4 -> 3x - 4*(-9/4) = 10 -> 3x + 9 = 10 -> 3x = 1 -> x = 1/3
What is the slope of the equation 3x plus 4y equals 8?
It is:- 3x+4y = 8 4y = -3x+8 y = -0.75x+2 So the slope is -0.75 and the y intercept is 2
X equals 4y and 3x - 2y equals 20?
(8, 2)
How do you graph 4y equals 8-3x?
Sensible but hard to explain
What would the graph look like for the line 3x plus 4y equals 8?
3x+4y = 8 4y = -3x+8 y = -3/4x+2 in slope intercrpt form It has a negative slope so the straight line goes 'downhill'
What would x and y be if the equation is 3x-4y equals 10 and -3x equals 4y equals 8?
3x - 4y = 10-3x - 4y = 8 -> add line 1 to line 2 3x - 4y = 100x - 8y = 18 -> -8y = 18 -> y = -18/8 = -9/4 -> 3x - 4*(-9/4) = 10 -> 3x + 9 = 10 -> 3x = 1 -> x = 1/3
What equation is equivalent to 3x-4y equals 8?
3x - 4y = 8Solve for x:3x = 4y + 8x = 4/3y + 8/3Solve for y:-4y = -3x + 8y = 3/4x - 2
What is equivalent to 3x-4y equals 8?
3x-4y = 8 -4y = -3x+8 y = 3/4x-2 or y = 0.75x-2 which is the equivalent in slope intercept form
What is the slope of the equation 3x plus 4y equals 8?
It is:- 3x+4y = 8 4y = -3x+8 y = -0.75x+2 So the slope is -0.75 and the y intercept is 2
X equals 4y and 3x - 2y equals 20?

How do you graph 4y equals 8-3x?
Sensible but hard to explain
What would the graph look like for the line 3x plus 4y equals 8?
3x+4y = 8 4y = -3x+8 y = -3/4x+2 in slope intercrpt form It has a negative slope so the straight line goes 'downhill'
Solve the system of equations 3x plus 4y equals 12 2x plus 4y equals 8?
x = 4 and y = 0
What equation is equivalent to 3x - 4y 8?
3x - 4y = 8Solve for x:3x = 4y + 8x = 4/3y + 8/3Solve for y:-4y = -3x + 8y = 3/4x - 2
What equations are equal to 3x-4y equals 8?
Straight line equations:- And if: 3x-4y = 8 Then: y = 0.75x-2 whereas 0.75 or 3/4 is the slope and -2 is the y intercept
X plus 2y equals 8 3x - 4y equals 10?
Multiply the first equation by -3
X equals -4y 3x plus 2y equals 20?
x = -4y so 3x = -12y Substituting in the second equation, -12y + 2y = 20 or -10y = 20 ie y = -2 And then x = -4y implies that x = 8 Solution: x = 8, y = -2
