Final Review - 1st Semester-Algebra 1A

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, typically represented as a fraction (rise/run). It indicates how much y changes for a change in x.

Front

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

Back

The slope (m) can be calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is the opposite operation of multiplication?

Back

The opposite operation of multiplication is division.

Front

What is the value of x in the equation 3x = 12?

Back

x = 4, found by dividing both sides by 3.

Front

How do you evaluate an expression with a variable?

Back

Substitute the value of the variable into the expression and perform the arithmetic operations.

Front

Evaluate the expression 20 - 3x + x² when x = 5.

Back

The result is 30.

Front

What is the solution to the equation y - 17 = -37?

Back

y = -20, found by adding 17 to both sides.

Front

What does it mean to simplify an expression?

Back

To simplify an expression means to combine like terms and reduce it to its simplest form.

Front

Combine like terms in the expression 7h + 10 + 3h + 7 - 6h + 2c.

Back

The simplified expression is 4h + 17 + 2c.

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed, typically in the form y = mx + b.
