Review: Literal Equations

Front

What is a literal equation?

Back

A literal equation is an equation that contains two or more variables.

Front

What is the first step to isolate a variable in an equation?

Back

Identify the operation being performed on the variable and perform the inverse operation.

Front

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

Back

'm' represents the slope of the line.

Front

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

Back

'b' represents the y-intercept of the line.

Front

How do you solve for x in the equation y = mx + b?

Back

Subtract b from both sides and then divide by m: x = (y - b)/m.

Front

What is the formula for distance in terms of rate and time?

Back

D = rt, where D is distance, r is rate, and t is time.

Front

How do you solve for t in the equation D = rt?

Back

t = D/r.

Front

What is the formula for area of a rectangle?

Back

A = LW, where A is area, L is length, and W is width.

Front

How do you solve for w in the equation A = LW?

Back

w = A/L.

Front

What is the formula for the slope of a line?

Back

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