Y=MX + B Review

Front

What is the general form of a linear equation?

Back

The general form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

Front

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

Back

'm' represents the slope of the line, indicating the steepness and direction of the line.

Front

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

Back

The y-intercept is the value of y when x = 0, represented by 'b' in the equation.

Front

How can you determine if a function is linear?

Back

A function is linear if it can be represented by a straight line on a graph, meaning it has a constant slope.

Front

What does it mean if a function is nonlinear?

Back

A nonlinear function does not form a straight line when graphed and may have curves or bends.

Front

If the slope 'm' is negative, what does that indicate about the line?

Back

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

Front

If the slope 'm' is positive, what does that indicate about the line?

Back

A positive slope indicates that the line ascends from left to right.

Front

What is the slope of the line represented by the equation y = 3x + 2?

Back

The slope of the line is 3.

Front

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

Back

The y-intercept of the line is 1.

Front

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

Back

The slope is calculated using the formula m = (y2 - y1) / (x2 - x1).
