Front

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

Back

Slope

Front

Identify the slope and y-intercept of the equation y = 1/5x + 5.

Back

Slope: 1/5, Y-intercept: 5

Front

Write the equation of the line with slope 3/5 that passes through the point (0, 1).

Back

y = (3/5)x - 1

Front

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

Back

y + 1 = -3(x + 2)

Front

Which of these represents point-slope form of a linear equation?

Back

y - y₁ = m(x - x₁)

Front

What is the y-intercept in the equation y = mx + b?

Back

The value of b.

Front

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

Back

Use the point (x₁, y₁) and the slope m.

Front

What is the formula for calculating the slope between two points (x₁, y₁) and (x₂, y₂)?

Back

m = (y₂ - y₁) / (x₂ - x₁)
