Question 669291: The formula for the slope of a line is given by: Identify ALL true statements about the slope formula.

1. The x and y values represent the x and y intercepts of the two different linear equations.

2. The subscripts 1 and 2 refer to two different points that are on the graph of the linear equation.

3. The x and y values represent the x and y coordinates of one point that is on the graph of the linear equation and one that is NOT on the graph of the linear equation.

4. The x and y values represent the x and y coordinates of two solutions of the linear equation.

5. The subscripts 1 and 2 refer to the two intercepts of the linear equation.

Null statement that makes no sense: ...and should always be larger in value than and since they appear first in the formula.

Question 669418: Okay, First of all here is the question. "Graph the following quadratic equation ."
I am learning on how to graph quadratic equations using the following formula and in the assignment. Being that H=x the axis of symmetry and (h,k) is the vertex. How do I graph this? This is what I have done so far.

A=1
B=4
C=0
Now using the following formula I can find if the parabola has what type of points.
b2-4ac means = 16 meaning has to equal points right? I am not sure this is where I am confused...
If my work here didn't make any sense just ignore it.
Thank you so much.
