8th grade quiz for those that don't study or review.

What is the correct formula for slope from a graph?

• Slope = rise x run 

• run + run /  72 = Slope

• Slope = rise / run

• y,x / x,y = Slope

What does the atomic number of an element also determine?

• Size of the element and where it would be found

• What type of element and the color

• The number of electrons and protons

• The number of shells and the column

What is the correct formula for slope from two points?

• Slope = (x1 / x2) x (y1 / y2)

• Slope = y2 - y1 / x2 - x1

• Slope = 182 - y x 2

Which is the correct atomic number for He?

• 1

• 34

• 5

• 2

Which is the correct equation to plug your numbers into to find the slope using two points?

• $\left(y1-x2\right)x\left(y2-x1\right)$

• $y1\ -\ x2\ +\ y2-x1$

• $\frac{y1-x1}{y2-x2}$

• $\frac{y2-y1}{x2-x1}$

Which answer choice tells you the correct determination of the acronym you learned to help with the Identify the atomic number? Remember A = atomic number, M = mass, N = neutrons, E = electrons

• $P\ =\ protons\ x\ M=\ mass$

• A = P = E      M = A - N

• $\frac{34}{\Pr otons}$

• M = A = P      E = N - A
