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

Back

y - y₁ = m(x - x₁)

Front

Convert the equation y + 5 = -3(x - 6) to slope-intercept form.

Back

y = -3x + 13

Front

Write the equation in point-slope form for the line that passes through the point (-2, -1) with a slope of -3.

Back

y + 1 = -3(x + 2)

Front

What does 'm' represent in the point-slope form of a linear equation?

Back

Front

What is the slope-intercept form of a line?

Back

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

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

Back

m = (y₂ - y₁) / (x₂ - x₁)
