ALGEBRA Semester 1 REVIEW

Front

Solve: 6(5x - 3) + 2 = 14

Back

Front

Solve the following system by SUBSTITUTION: x + y = -6, y = 2x - 4. What is the solution?

Back

(-2, -4)

Front

Solve: 32 - 7x = -6(x + 3)

Back

50

Front

Is the relation a function? Why: {(11, 2), (11, 3), (2, 4)}

Back

No, because the x-value 11 has two y-values pair with it.

Front

Find the slope of the line that passes through (10, 1) and (5, 2)

Back

-1/5

Front

What is the definition of a function?

Back

A relation where each input (x-value) has exactly one output (y-value).

Front

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

Back

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

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does it mean for two lines to be parallel?

Back

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

Front

What is the solution to the equation 3x + 5 = 20?
