Review: 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 represented by the equation y + 1 = -3(x - 5)?

Back

-3

Front

Write the equation of the line in point-slope form that passes through (10, 5) with a slope of -3.

Back

y - 5 = -3(x - 10)

Front

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

Back

y = mx + b

Front

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

Back

m = (y₂ - y₁) / (x₂ - x₁)
