Complete the ordered pair for the equation y equals -9x plus 6?
-9x+6=y (swap over +6 and y) -9x-y=-6 (when u move numbers or letters over d equal sign u need 2 change signs) 9x+y=6 (chaned all signs) y= 6-9 y= -3 9x+y=6 9x+-3=6 9x=6+3 9x=9 x=9(divided by) 9 x=1 9x+y=6 9+-3=6 So the ordered pair is (1,-3)
What is the orderedpair for 9x-3y equals 63 and 7x-3y equals 45?
9x-3y=63 7x-3y=45 -3y=63-9x -y=21-3x y=-21+3x 7x-3(-21+3x)=45 7x+63+9x=45 7x+9x=45-63 16x=-18 x=-1.125 y=-21+3(-1.125) y=-24.375 (-1.125,-24.375)
What is the relationship 3x - 3y equals -9 and 9x - 9y equals -27?
3x-3y=-9 and 9x-9y=-27 both simplifies to x-y=-3.
How do you solve 2x-y equals -6 and 2x plus 3y equals 9?
2x + 3y = 9x = 3, y = 1 therefore 6 + 3 = 9
What is the y intercept to 9x plus 3y equals -54?
9x + 3y = -54 3y = -9x - 54 y = -(3x + 18) Therefore, the y-intercept of this equation is y=-18.

What is the y intercept of the line y equals 9x plus 3?
The y intercept would be 3.
If x equals 6 and y equals 3 then 9x plus 8y equals?
9x + 8y = (9 x 6) + (8 x 3) = 54 + 24 = 78
2y-9x equals 14 solve for y?
2y - 9x = 14 2y = 14 + 9x y = (14 + 9x) / 2
If x equals 10 and y equals 10 then 9x plus 8y equals?
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
How can you get coefficients that are equal for y. 3x plus 5y equals 7 2x plus 15y equals 11?
Multiply the first equation by 3 to give 9x + 15y = 21
What is the orderedpair for 9x-3y equals 63 and 7x-3y equals 45?
9x-3y=63 7x-3y=45 -3y=63-9x -y=21-3x y=-21+3x 7x-3(-21+3x)=45 7x+63+9x=45 7x+9x=45-63 16x=-18 x=-1.125 y=-21+3(-1.125) y=-24.375 (-1.125,-24.375)
What is the slope of the line 9x - 3y equals 10?
In the equation y = mx + b, m is the slope. To convert 9x - 3y = 10 to y = mx + b: 9x - 3y = 10 Subtract 9x from both sides: -3y = -9x +10 Divide both sides by -3: y = 3x - 10/3 The slope of this line is 3.
What is the relationship 3x - 3y equals -9 and 9x - 9y equals -27?
3x-3y=-9 and 9x-9y=-27 both simplifies to x-y=-3.
How do you solve 2x-y equals -6 and 2x plus 3y equals 9?
2x + 3y = 9x = 3, y = 1 therefore 6 + 3 = 9
What is the y intercept to 9x plus 3y equals -54?
9x + 3y = -54 3y = -9x - 54 y = -(3x + 18) Therefore, the y-intercept of this equation is y=-18.
Is y plus 7 equals 3x and 9x-y equals -7 parallel with each other?
No because they don't have the same slope (9x & 3x)
