Front

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

Back

y-intercept

Front

What is the formula to calculate the perimeter of a rectangle?

Back

Perimeter = 2(length + width)

Front

If a soccer field is 100 meters long and 50 meters wide, what is its perimeter?

Back

300 meters

Front

What is the formula for the area of a rectangle?

Back

Area = length × width

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

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

Back

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

Front

What is the slope of the line that passes through the points (8, 4) and (5, 3)?

Back

1/3

Front

What is the equation of a line with slope m and y-intercept b?

Back

y = mx + b

Front

If m = -3 and b = 5, what is the equation of the line?

Back

y = -3x + 5

Front

What does the term 'circumference' refer to in geometry?

Back

Circumference is the distance around a circle.
