Question:

What is the difference between Overloading and Overriding? And which one is an example of polymorphism?

Ebony C.

Answer:

Overloading is when methods have the same name but different parameters being passed in and overriding is when methods from a super and sub class have the same name and parameters. Overriding is an example of polymorphic behavior because even though the method signatures are identical based on the object calling the method the correct method from the super or sub class will be called.

Question:

Find the slope of the given line, the x-intercept, and the y-intercept: 2x + 3y = 2

Ebony C.

Answer:

1. Rewrite the equation in slope-intercept form y = mx +b -Move the 2x to the right by subtracting 2x on both sides => 2x + 3y -2x = 2 - 2x -Divide both sides by 3 => (3y/3) = ((2-2x)/3) - Slope-intercept equation: y = -(2/3)x +(2/3) 2. The slope is the value in front of x, the slope is -(2/3) 3. The y-intercept is the constant at the end, the y-intercept is 2/3 4. The x-intercept can be found by plugging in 0 for y and solving for x=> 0 = -(2/3)x +(2/3) (2/3)x = (2/3) the x-intercept is 1
