If: 4x-7y-28 = 0 then y = 4/7x-4 whereas 4/7 is the slope and -4 is the y intercept
If you mean: 32-10x+7y = 0 then as a straight line equation it is 7y = 10x-32
Will try elimination here.2X - 7Y = 0- 2(X - 6Y = - 5)2X - 7Y = 0- 2X + 12Y = 10------------------------------add5Y = 10Y = 2---------- find X ( second equation will do )X - 6(2) = - 5X - 12 = - 5X = 7-------------check both equations for consistancy2(7) - 7(2) = 014 - 14 = 00 = 0----------------first equation checks7 - 6(2) = - 57 - 12 = - 5- 5 = - 5---------------------------both check and are consistent(7, 2)------------------ordered pair
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
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
6y=5y+2y 6y=7y that does't work its unequal -
5x - 7y = -35At the x-intercept, y=0:5x = -35x = -7At the y-intercept, x=0:-7y = -35y = 5
7y+3x-21 =0 7y = -3x+21 y = -3/7x+3 The y intercept is 3
x=0 and y=12\7
2y - 7 + 5y = 0 Collecting like terms together, 7y - 7 = 0 or 7y = 7 So that y = 1
y2+7y=18 y2+7y-18=0 (y+9)(y-2)=0 y=-9 & y=2
3
If: 4x-7y-28 = 0 then y = 4/7x-4 whereas 4/7 is the slope and -4 is the y intercept
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= ___
6x+7y=-6 3(-2x-3y=2) +________ -2y=0 => y=0 Therefore x=-1
(4, -7)
It works out that they intersect at: (4, -7)
