How do you find the slope from a graph?

• Subtract the Y intercept from the X intercept

• Multiply the X and Y intercepts

• Divide the change in Y by the change in X

• Add the coordinates of any two points

What represents the y-intercept in a table?

• The value of Y when X is 1

• The value of Y when X is 0

• The value of X when Y is 0

• The highest value of Y

What is a common issue when trying to find the slope in tables provided by computer programs?

• The table only shows positive numbers

• The X values decrease

• The Y values are constant

• The X values do not increase uniformly

How can you simplify finding the y-intercept in complex tables?

• By creating a new table with X values increasing by 1

• By only using the highest X and Y values

• By calculating the average of all Y values

• By ignoring the Y values

What is the y-intercept if the table starts with the point (1, 5)?

• 7

• 3

• 1

• 5

Why is it important to compare linear functions in different forms?

• To make it easier to graph them

• To understand their applications in real life

• To identify which function has the higher slope or y-intercept

• To find which form is the easiest to use
