Algebra 1 Part 1 Review - Equations and Slope

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. It is represented as (0, b) in the equation of a line y = mx + b.

Front

Solve the equation: 4 - 6x - 2 = -2(3x - 1)

Back

Infinitely many solutions.

Front

What is the slope in the equation y - 2x = 3?

Back

The slope is 2.

Front

Solve the equation: 3x - x + 4 = 4(2x + 1)

Back

x = 0.

Front

What is the y-intercept in the following equation: y = -4x - 5?

Back

The y-intercept is -5.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x, indicating how steep the line is.

Front

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

Back

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

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.

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 does it mean if two lines are perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.
