Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, typically represented as 'm' in the slope-intercept form of a linear equation, which is defined as the change in y over the change in x (rise over run).

Front

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

Back

The slope (m) can be calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

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

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the y-intercept represent in a graph?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of 'b' in the slope-intercept form.

What does the inequality y ≥ 3 represent on a graph?

Back

It represents all points on the graph where the y-value is greater than or equal to 3, including the line y = 3.

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed, typically in the form y = mx + b.

Front

What is the difference between '>' and '≥' in inequalities?

Back

'>' means greater than (not including the boundary), while '≥' means greater than or equal to (including the boundary).

Front

What is a haberdasher?

Back

A haberdasher is someone who deals in men's fashion, particularly men's clothing and accessories.

How do you simplify the expression 2(x + 3) + 4?

Back

By distributing, you get 2x + 6 + 4, which simplifies to 2x + 10.
