Identifying the m and b from an Equation

Front

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

Back

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

Front

How do you identify the slope (m) from the equation y = mx + b?

Back

The slope (m) is the coefficient of x in the equation.

Front

How do you identify the y-intercept (b) from the equation y = mx + b?

Back

The y-intercept (b) is the constant term in the equation, where the line crosses the y-axis.

Front

If m = 2 and b = -3, what is the equation of the line?

Back

y = 2x - 3

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises as it moves from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls as it moves from left to right.

Front

What is the slope of the line represented by the equation y = 4x + 1?

Back

The slope (m) is 4.

Front

What is the y-intercept of the line represented by the equation y = -5x + 2?

Back

The y-intercept (b) is 2.

Front

How would you write the equation of a line with a slope of -1 and a y-intercept of 4?

Back

y = -1x + 4 or y = -x + 4.

Front

What is the slope of the line represented by the equation y = 0.5x - 3?

Back

The slope (m) is 0.5.
