2y equals 8x - 14 4y equals 8x plus 4?
x=4, y=9 (4,9)
If 8x plus 4y equals 16 what is the slope?
If 8x + 4y = 16, then y = - 2x + 4 Thus the slope is -2 and the intercept is 4.
How do you solve -8x plus 4y equals 28 for y?
-8x + 4y = 28 Add 8x to each side: 4y = 8x + 28 Divide both sides by 4: y = 2x + 7
What is the point of contact between the line y equals x plus 4 and the circle x2 plus y2 -8x plus 4y equals 30?
Equations: y = x+4 and x^2 +y^2 -8x +4y = 30 It appears that the given line is a tangent line to the given circle and the point of contact works out as (-1, 3)
Are 3x-4y equals -5 and 8x plus 6y equals -5 parallel or perpendicular lines?
They are perpendicular lines because the slopes are 3/4 and -4/3 respectively.
2y equals 8x - 14 4y equals 8x plus 4?

How do you solve -8x plus 4y equals 28 for y?
-8x + 4y = 28 Add 8x to each side: 4y = 8x + 28 Divide both sides by 4: y = 2x + 7
If x equals 5 and y equals 5 then 8x plus 4y equals?
(8 + 4) x 5...
3x-3y equals 12 4y-8x equals -16?
(0,-4)
What is the point of contact between the line y equals x plus 4 and the circle x2 plus y2 -8x plus 4y equals 30?
Equations: y = x+4 and x^2 +y^2 -8x +4y = 30 It appears that the given line is a tangent line to the given circle and the point of contact works out as (-1, 3)
Are 3x-4y equals -5 and 8x plus 6y equals -5 parallel or perpendicular lines?
They are perpendicular lines because the slopes are 3/4 and -4/3 respectively.
Is this pair of lines parallel 3x-4y equals -3 and 8x plus 6y equals 14?
Put in this form to see. Y = mX + c 3X - 4Y = - 3 - 4Y = - 3X - 3 Y = (3/4)X + 3/4 --------------------- 8X + 6Y = 14 6Y = - 8X + 14 Y = (- 4/3)X + 7/3 ----------------------- Closer to perpendicular than anywhere near parallel!
How do you graph 8x equals 4y?
4y = 8x Divide each side by 4: y = 2x Draw a straight line, through the origin, with a slope of +2 .
How do you Simplify 4x plus 12 over 8x - 4y?
(4x + 12)/(8x - 4y) = [4(x) + 4(3)]/(4(2)(x) - 4y] = 4(x + 3)/4(2x - y) = (x+ 3)/(2x - y)
6x - 4y equals -8 11x plus 4y equals 76?
(4, 8)
Solve this equation using subtitution 8x subtract y equals 4 and 5x plus 3y equals 17?
y=4x=1Because:8x - y = 45x + 3y = 17You can rearrange the first equation to give:y = 8x - 4And substitute this into the second equation:5x + 3(8x - 4) = 17Expanded out:5x + 24x - 12 = 1729x - 12= 1729x = 29So x=1And because you know know x you can put that into an equation to find y:y = 8x - 4y= 8 - 4y= 4
