Front

What type of line is used when graphing an inequality with the symbols < or >?

Back

A dotted line is used.

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, y).

Front

Back

x = 10

Front

Solve for x: 7x = 3x + 24

Back

x = 6

Front

Solve for x: 2x = x + 3

Back

x = 3

Front

What does it mean to solve an equation?

Back

To find the value(s) of the variable that make the equation true.

Front

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

Back

The slope-intercept form is 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

The slope m is calculated as m = (y2 - y1) / (x2 - x1).

Front

What is the difference between a solid line and a dotted line when graphing inequalities?

Back

A solid line indicates that the points on the line are included (≤ or ≥), while a dotted line indicates they are not included (< or >).

Front

What is the solution set of an inequality?

Back

The solution set is the set of all values that satisfy the inequality.
