7x + y = 4y = 4 - 7x
If you mean: y=7x -3 then it is a proportional relationship of a straight line equation.
The expression can be simplified to: 7x+4y
Funtion: 7x-3y+42 => y=7/3x - 14 x-intercept: (6,0) y-intercept: (0,-14)
7X - 12Y = 96 - 12Y = - 7X + 96 Y = (7/12)X - 8 ============== m = 7/12 Y intercept = - 8
7x + y = 4y = 4 - 7x
y=7x
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
The Y intercept of y=7x+10 is 10.
7x + y + z = 6 7x + y + 4z = 9 y + x = 6 Take the first two statements and subtract them. 7x + y + z = 6 7x + y + 4z = 9 _____________ 0 + 0 - 3z = -3 Therefore: z = 1 Then you are left with: 7x + y + 1 = 6 7x + y + 4 = 9 which is impossible, so this is an impossible equation.
7x+y=6
7x +y = 6
If you mean: y = -7x then the slope is -7 and there is no y intercept
7x + y = 6 y = 6 - 7x dy/dx = 0-7 = -7 Slope = -7
y = -7x 0 = -7x 0 = x x-intercept point is (0, 0).
3x+7x+3+y= 10x+3+y
