Point Slope and Slope Intercept Review

Front

What type of line has a slope of 0?

Back

A horizontal line.

Front

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

Back

y - y₁ = m(x - x₁)

Front

What is the equation of a line when m = -3 and b = 5?

Back

y = -3x + 5

Front

What type of line has an undefined slope?

Back

A vertical line.

Front

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

Back

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

Front

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

Back

Slope (m) = (y₂ - y₁) / (x₂ - x₁).

Front

What does the 'm' represent in the equation y = mx + b?

Back

The slope of the line.

Front

What does the 'b' represent in the equation y = mx + b?

Back

The y-intercept of the line.

Front

If a line passes through the point (2, 3) and has a slope of 4, what is its equation in point-slope form?

Back

y - 3 = 4(x - 2).

Front

Convert the point-slope equation y - 1 = 2(x - 3) to slope-intercept form.

Back

y = 2x - 5.
