What is an equation for the line that passes through the coordinates (-1,2) and (7,6)  ?

• y = (1/2)x + 2.5
• y = (1/2)x - 5
• y = 3x + 4
• y = -3x + 4

Write an equation in slope-intercept form from the points (-4, 0) and (1, 5)

• y = x - 4
• y = x + 4
• x = y + 4
• y = 4x + 4

Write an equation in slope-intercept form from the points (0, 5) and (4, 3)

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

Given the table, write the equation in the slope-intercept form.

• y = 1/3x + 6
• y = 3x + 6
• y = 2x + 6
• y = 1/2x + 6

_{What is the y-intercept of the line?}

• y = 1/2
• y = 1
• y = -1/2
• y = -1

A rental company at Best Bargain Rental costs $150 a week, plus $0.10 per mile.  Which equation represents the relationship between the number of miles (x) and the total cost in dollars (y) for a 2- week period?

• y = 2(150)(0.10x)
• y = 2(150) + 0.10x
• y = 150 + 2(0.10x)
• y = 2(150 + 0.10x)
