Given that the equation is a straight line we know that it will take the form of y = mx + c with m as the gradient and c as the y-intercept. We can find the slope by doing (y₁- y₂)/(...

pi x r² x height

Answer:x=-2, y=-3 or x=2, y=3
Explanation:We can rewrite 2xy=12 as (2y)x=12, and since we know that 2y=3x, we can substitute this in to get the following equation: 3x^2 = 12. Solving this we get that...
