Front

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

Back

y - y₁ = m(x - x₁), where (x₁, y₁) is a point on the line and m is the slope.

Front

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

Back

The slope of the line.

Front

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

Back

The y-intercept of the line.

Front

Convert the equation 5x - 3y = 15 to slope-intercept form.

Back

y = (5/3)x - 5.

Front

What is the slope of the line represented by the equation y = -1x + 2?
