Multiply the numerators together and the denominators to get the ending fraction.
Ex: 3/4 x 3/4 = 9/16, and simplify if needed.
Differentiation is part of calculus
differentiation basically allows you to find the gradient of tangent
The answer is D. Note that the y-intercept is -3, not 3. So, when x is at 0, y should be -3. Choice D is the only graph with a y-intercept of -3.
Yes, it is a linear equation.
