Algebra 1 EOC Review 1

Front

What is the equation of a line in slope-intercept form?

Back

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

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the slope of a line that is perpendicular to a line with a slope of 5?

Back

-1/5.

Front

What are opposite reciprocals in relation to slopes of perpendicular lines?

Back

If one line has a slope of m, the slope of the line perpendicular to it is -1/m.

Front

If Bob saves $40 per month starting with $150, what is the equation for his savings after x months?

Back

y = 40x + 150.

Front

What does the term 'y-intercept' refer to in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis (x=0).

Front

How do you solve for a variable in an equation?

Back

Isolate the variable on one side of the equation using inverse operations.

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are integers.

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 formula for the slope of a line given its equation in standard form?

Back

Slope (m) = -A/B from the equation Ax + By = C.
