Functions, forms, and writing linear equations

Which graph represents y as a function of x? (Hint: Draw a vertical line; if it passes a graph more than once, the graph is not a function)

Match the following linear function forms.

• Point-slope form

• Slope-intercept form

• Standard form

Match the following quadratic functions with their right forms.

• Factored form

• Standard form

• Vertex form

Which ones represent as functions? Select all correct answers (x values in a table cannot be repeated but y values can. Focus on x values only to see if they are repeating)

If two linear functions are parallel to each other, then their slopes must be:​ (a)  

• same sign, same value
• same sign, different value
• different
• different sign, same value
• different sign, different value

If two linear functions are perpendicular to each other, their slopes must be:​ ​ (a)  

• Negatively reciprocal (opposite)
• don;t know
• 234

Slope is 5 and y-intercept is 2, what is a linear function in the form of slope-intercept form?
