Semester 1 Final Exam Review

Front

What is the value of f(-3) if f(x) = 2?

Back

f(-3) = 2

Front

Solve the equation: 2x + 7 = 11

Back

x = 2

Front

What does 'm' represent in the equation y = mx + b?

Back

m represents the slope of the line.

Front

Solve the system of equations: y = -3x + 5 and 5x - 4y = -3

Back

The solution is (1, 2).

Front

Solve the equation: 6x + 1 = -6(1 - x)

Back

There is no solution.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope m is calculated as m = (y2 - y1) / (x2 - x1).

Front

What is the y-intercept in the equation y = 3x + 4?

Back

The y-intercept is 4.

Front

What does it mean if two lines are parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What is the solution to the equation x^2 - 4 = 0?

Back

The solutions are x = 2 and x = -2.
