Algebra Graphing Keystone Practice

Match the system to the graph (solution set is on the left)

• y ≤ 3x   and  y ≤ -2x + 4

• y > 3x   and  y > -2x + 4

• y < 3x   and  y > -2x + 3

• y > 3x   and  y < -2x + 4

Which of the following is not a solution to this system of inequalities?

• (0,-1)

• (0,3)

• (4,0)

• (6,-2)

Write an equation in slope-intercept form of the line that passes through the given points: (-4,-7) and (-6,9)

• y = 8x + 39

• y = -8x - 39

• y = -8x - 32

• y = 8x + 32

Which graph represents a function?

• 
• 
• 
• 

Which graph is a function?

• Graph 1

• Graph 2

• Graph 3

• Graph 4

Which statement about the relation is true?

• The relation is not a function of x because all functions are linear

• The relation is a function of x because values of x increase towards infinity

• The relation is a function of x because each value of y corresponds to one value of x

• The relation is not a function of x because more than one value of y may correspond to the same value of x

Darlene is collecting prize tickets. The equation y = 2x + 1 describes the relationship between the number of days (x) since she began collecting and the number of prize tickets (y) she has collected. Which statement correctly describes a solution to the system?
