Point-Slope Formula

Front

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

Back

y - y₁ = m(x - x₁)

Front

What does 'm' represent in the equation y - y₁ = m(x - x₁)?

Back

Slope

Front

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

Back

Isolate y to get y = mx + b.

Front

Given the point (2, 3) and slope m = 4, write the point-slope form of the equation.

Back

y - 3 = 4(x - 2)

Front

What is the slope-intercept form of the equation with slope m = -2 and y-intercept b = 5?

Back

y = -2x + 5

Front

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

Back

m = (y₂ - y₁) / (x₂ - x₁)
