Give the equation for the graph

• y = 5x - 3
• y = 4x + 2
• y =-2x + 5
• y = - 2x + 4

y=2x+4; find the slope 

• -2
• 2
• 1/2
• 4

y=6-2/7x; find the slope

• 0
• 2
• 6
• -2/7

• f(x) because its rate of change is 4 while the rate of change for g(x) is 2 
• g(x) because  its rate of change is 4 while the rate of change for f(x) is 2
• g(x) because its graph appears steeper than that of f(x)
• Neither, both graphs appear to rise at the same rate 

Equation A: y = 3x - 1
Equation B: y = 1/2x + 1
Which equation has a higher y intercept? 

• Equation A
• Equation B
• They have the same Y intercept

Which company shows a greater rate of change?

• Water's Edge Rafts
• Ryan's Rafts
