Front

Solve: 6x + 10 > 5x - 12

Back

x > -22

Front

Solve: 3(x - 2) < 2(x + 9)

Back

x < 24

Front

Solve for x and y: 3x + 2y = 16; 7x + y = 19

Back

(2, 5)

Front

Which is the point-slope form of an equation for the line that passes through (0, -5) with slope 2?

Back

y + 5 = 2x

Front

Find the slope-intercept form of an equation for the line that passes through (-1, 2) and is parallel to y = 2x - 3.

Back

y = 2x + 4

Front

What is the definition of a linear equation?

Back

An equation that makes a straight line when graphed, typically in the form y = mx + b.

Front

What does the slope of a line represent?

Back

The rate of change of y with respect to x; it indicates the steepness and direction of the line.

Front

What is the y-intercept of a line?

Back

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

Front

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

Back

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

Front

What is the difference between parallel and perpendicular lines?

Back

Parallel lines have the same slope and never intersect; perpendicular lines have slopes that are negative reciprocals of each other.
