Front

What is the y-intercept in a graph?

Back

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

Front

How do you identify the y-intercept from a table of values?

Back

Look for the value of y when x is 0; this value is the y-intercept.

Front

What does the variable 'b' represent in the equation of a line (y = mx + b)?

Back

The variable 'b' represents the y-intercept of the line.

Front

What is the difference between proportional and non-proportional relationships?

Back

Proportional relationships pass through the origin (0,0), while non-proportional relationships do not.

Front

If a line has a y-intercept of 5, what does this mean?

Back

It means that when x = 0, the value of y is 5, so the point (0, 5) is on the line.

Front

How can you determine if an equation is proportional?

Back

An equation is proportional if it can be written in the form y = kx, where k is a constant.

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

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

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

Back

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

Front

What is a linear equation?

Back

A linear equation is an equation that forms a straight line when graphed.
