Front

What is the formula to calculate speed?

Back

Speed = Distance / Time

Front

What is slope-intercept form of a linear equation?

Back

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

Front

How do you find the length of a line segment in a triangle?

Back

Use the distance formula or Pythagorean theorem if applicable.

Front

What does the initial value represent in a linear equation?

Back

The initial value (b) is the y-coordinate where the line crosses the y-axis.

Front

How do you convert a repeating decimal to a fraction?

Back

Let x = the decimal, multiply by a power of 10 to shift the decimal, then solve for x.

Front

What is the constant rate of speed if a car travels 390 miles in 6 hours?

Back

65 miles per hour.

Front

What is the slope of a line?

Back

The slope (m) is the ratio of the rise (change in y) over the run (change in x).

Front

What is the significance of the y-intercept in a graph?

Back

It indicates the value of y when x = 0.

Front

How do you determine the distance between two points on a coordinate plane?

Back

Use the distance formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the relationship between the slope and the steepness of a line?

Back

A larger absolute value of the slope indicates a steeper line.
