Algebra 1 EOC Review 1

Front

What are the slopes of parallel lines?

Back

The slopes of parallel lines are the same.

Front

Write the equation of the line with a slope of -3 and a y-intercept of -3.

Back

y = -3x - 3

Front

If a holiday meal costs $12.50 per person plus a delivery fee of $30, what equation represents the total cost for x people?

Back

y = 12.5x + 30

Front

What are the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are opposite reciprocals.

Front

Solve for a: a = pw. What is the formula for p?

Back

p = a/w.

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 does it mean for two lines to be perpendicular?

Back

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

Front

If the slope of a line is 2, what is the slope of a line perpendicular to it?

Back

The slope of a line perpendicular to it is -1/2.
