Point-Slope Form

Front

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

Back

y - y₁ = m(x - x₁)

Front

What does 'm' represent in the point-slope form?

Back

The slope of the line.

Front

What does (x₁, y₁) represent in the point-slope form?

Back

A specific point on the line.

Front

How do you convert point-slope form to slope-intercept form?

Back

Isolate y to get y = mx + b.

Front

What is the slope of the line that passes through the points (2, 3) and (4, 7)?

Back

2

Front

What is the slope of a line that is horizontal?

Back

0 (zero slope).

Front

What is the slope of a line that is vertical?

Back

Undefined.

Front

If a line has a negative slope, what does that indicate about its direction?

Back

The line decreases as it moves from left to right.

Front

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

Back

y = mx + b.

Front

What does 'b' represent in the slope-intercept form?

Back

The y-intercept of the line.
