x-intercept = 2; y-intercept = 6

Front

Back

The slope of a parallel line is the same, so it is 2.

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2(length + width)

Front

If the length of a rectangle is 2 times 3 less than the width, how can this be expressed algebraically?

Back

Length = Width - 6

Front

How do you calculate the time it takes for a decreasing water level?

Back

Time = (Initial Level - Final Level) / Rate of Decrease

Front

What is the equation of a line in slope-intercept form?

Back

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

Front

How do you find the x-intercept of an equation?

Back

Set y = 0 and solve for x.

Front

How do you find the y-intercept of an equation?

Back

Set x = 0 and solve for y.

Front

What does it mean for two lines to be parallel?

Back

They have the same slope and will never intersect.

Back

Substituting x=2 gives 10(-0.5) = 3(2) - 11, which is true.
