What is the slope of 4x-7y-28 equals 0?
If: 4x-7y-28 = 0 then y = 4/7x-4 whereas 4/7 is the slope and -4 is the y intercept
What does 32-10x plus 7y equal?
If you mean: 32-10x+7y = 0 then as a straight line equation it is 7y = 10x-32
What ordered pair represents the solution to the system of equations2x-7Y equals 0 x-6Y equals -5?

What is the equation of the line whose intercepts are x is 7 and y is 11 showing work?
Points: (7, 0) and (0, 11) Slope: 0-11/7-0 = -11/7 Equation: y-0 = -11/7(x-7) => 7y = -11x+77 Equation: y-11 = -11/7(x-0) => 7y = -11x+77
What is the slope of 7y 3x - 21 0?
Without the inclusion of an equality sign or whether it is -210 rather than -21 0 it can't be answered. But if you meant: 7y = 3x-210 then y = 3/7x-30 where then the slope is 3/7 and the y intercept is -30
What is 6y equals 5y plus 2y?
6y equals 5y plus 2y can be simplified to 6y = 7y. To solve for y, subtract 7y from both sides of the equation, which gives 6y - 7y = 0. This simplifies to -y = 0, or y = 0.
What is the x and y intercepts of 5x-7y equals -35?
5x - 7y = -35At the x-intercept, y=0:5x = -35x = -7At the y-intercept, x=0:-7y = -35y = 5
What is the y-intercept in this linear equation 7y plus 3x - 21 equals 0?
7y+3x-21 =0 7y = -3x+21 y = -3/7x+3 The y intercept is 3
What is the answer to 3x-7y equals 12?
x=0 and y=12\7
What is the answer for 2y-7 plus 5y equals 0?
2y - 7 + 5y = 0 Collecting like terms together, 7y - 7 = 0 or 7y = 7 So that y = 1
What equation could be used to solve y² plus 7y equals 18 by factoring?
y2+7y=18 y2+7y-18=0 (y+9)(y-2)=0 y=-9 & y=2
What is th y intercept of 7y plus 3x-21 equals 0?
3
What is the slope of 4x-7y-28 equals 0?
If: 4x-7y-28 = 0 then y = 4/7x-4 whereas 4/7 is the slope and -4 is the y intercept
What is 18 equals 39-7y equal -with the work shown?
18=39-7y minus 18 from both sides (0=21-7y) subtract 21 from both sides to get the variable and the number on opposite sides -21=-7y -21/-7y= ____ y= ___
How would you solve 6xn plus 7y equals -6 -2x-3y equals 2 using addition method?
6x+7y=-6 3(-2x-3y=2) +________ -2y=0 => y=0 Therefore x=-1
What is the point of intersection of the lines 5x plus 7y plus 29 equals 0 and 11x minus 3y minus 65 equals 0?
(4, -7)
What is the point of intersection of the lines 5x plus 7y plus 29 equals 0 and 11x -3y -65 equals 0?
It works out that they intersect at: (4, -7)
