Algebra 1 Final Examination Part 1

Which line appears to have an x-intercept of 4 and y-intercept of -5?

• A

• B

• C

• D

Which graph represents a system with no solution?

• A

• B

• C

• D

The graph of a quadratic function is shown below. Which equation represents the axis of symmetry?

The water level of a bayou was measures each day over a tw-week period. The graph models the linear relationship between the water level of the bayou and the number of days the water level was measured. Which statement best describes the y-intercept of the graph?

• The initial water level was 12 ft.

• The water level was measured for 14 days.

• The water level increased by 1 foot every 14 days.

• The water level at the end of two weeks was 15.5 ft.

A system of equations is graphed on the grid. Which of the following represents the solution to the system of equations?

A graph of a quadratic function is shown on the grid. Which coordinates best represents the vertex of the graph?

• Divide both sides by 11

• Multiply both sides by 11.

• Add 11 to both sides.

• Subtract 11 to both sides.

Write an equation for the line shown by counting the slope and identifying the y-intercept.

• y = -2x + 2

• y = 2x + 2

• y = 1/2x- 2

• y = -1/2x + 2

Convert to the following equation to slope-intercept form:

5x + 3y = 12

• 3y = -5x + 12

• 5x = -3y + 12

• y = -5/3x + 4

• x = -3/5y + 12/5

Which of the following is an algebraic EXPRESSION?

• 3 + 17 − k

• 3x − 45 = b

• 25x = 80

• 9m + 4 > 13
