Math 3 Lessons 2.8 to 2.12 Flashcard (Linear EQ)

Front

What does 'b' represent in the slope-intercept form (y=mx+b)?

Back

The y-intercept.

Front

What does it mean for a table to be proportional?

Back

A table is proportional if the ratio of the values in one column to the values in another column is constant.

Front

What is the slope of a vertical line?

Back

Undefined.

Front

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

Back

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

Front

What is the slope of the line that passes through the points (2, 4) and (6, 12)?

Back

2.

Front

What is the y-intercept of a line?

Back

The y-coordinate where the line crosses the y-axis.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

The line is horizontal.

Front

If a line has a negative slope, what direction does it go?

Back

The line goes down from left to right.

Front

What is the slope of the line that passes through the points (8, -2) and (8, 4)?

Back

Undefined.

Front

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

Back

y = mx + b, where m is the slope and b is the y-intercept.
