Front

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

Back

m represents the slope of the line.

Front

What is the slope in the equation y=2x + 3?

Back

The slope is 2.

Front

Find the product: (y - 3)(y + 7)

Back

The product is y² + 4y - 21.

Front

Find the slope of the line that passes through (1, -19) and (-2, -7)

Back

The slope is -4.

Front

Match the inequality: y ≤ 2x - 4

Back

This represents a line where y is less than or equal to 2x - 4.

Front

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

Back

The y-intercept is the value of y when x=0.

Front

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

Back

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

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 standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.
