slope intercept form

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

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

Back

The 'b' represents the y-intercept, which is the point where the line crosses the y-axis.

Front

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

Back

The slope 'm' is the coefficient of x in the equation.

Front

If the slope of a line is negative, what does that indicate about the line's direction?

Back

A negative slope indicates that the line descends from left to right.

Front

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

Back

The slope of the line is 2.

Front

How can you convert the equation 3x + 2y = 6 into slope-intercept form?

Back

To convert, solve for y: 2y = -3x + 6, then y = -3/2x + 3.

Front

What is the y-intercept of the line y = -4x + 1?

Back

The y-intercept is 1.

Front

Which of the following equations has a slope of 1? y = x + 2, y = -x + 2, y = 2x + 1, y = 3x - 1

Back

y = x + 2 has a slope of 1.

Front

What does it mean if two lines are parallel in terms of their slopes?

Back

Two lines are parallel if they have the same slope.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.
