Front

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

Back

The slope of the line.

Front

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

Back

The value of y when x=0.

Front

What is the x-intercept in a linear equation?

Back

The value of x when y=0.

Front

What does a negative slope indicate about a line?

Back

The line decreases as it moves from left to right.

Front

What does a positive slope indicate about a line?

Back

The line increases as it moves from left to right.

Front

In the equation y=mx+b, what does 'b' represent?

Back

The y-intercept.

Front

How can you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are integers.

Front

What does it mean for two lines to be parallel?

Back

They have the same slope but different y-intercepts.

Front

What does it mean for two lines to be perpendicular?

Back

The product of their slopes is -1.
