Finding Slope and Y-Intercept: Key Concepts and Applications

What is the first step in finding the slope from a table?

• Label the columns as X and Y

• Find the change in Y values

• Simplify the slope

• Find the change in X values

How do you simplify the slope if the change in Y is 12 and the change in X is 50?

• 12/50 simplifies to 6/25

• 12/50 simplifies to 2/25

• 12/50 simplifies to 3/25

• 12/50 simplifies to 1/25

In a sequence, if the change is consistent, what is the first term called?

• Zero term

• First term

• Initial term

• Second term

If the rate of change is 5 and the first term is 7, what is the y-intercept?

• 5

• 7

• 2

• 0

What is the equation format used to find the slope and y-intercept?

• Y = bx + m

• Y = mx + b

• X = my + b

• X = by + m

If the rate of change is 1/2 and the first term is 1/4, what is the y-intercept?

• 1/2
