Yep! They are all right! Great job, could write a bit better.... sorry
<span>A system of equations has infinitely many solutions when the two
lines representing the equations coincide. i.e. the two equations are
the same or a multiple of each other.
2y - 4x = 6
2y = 4x + 6
2y = 2(2x + 3)
y = 2x + 3
-y = -(2x + 3)
-y = -2x - 3
Hence the other equation is -y = -2x - 3</span>
-3x^2 +10x
All you have to do is combine like terms!
Answer:
The gradient is 3/7 make y the subject. Then put the coordinates in the equation.
