Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the y-intercept of a linear equation?

Back

To find the y-intercept, set x = 0 in the equation and solve for y.

Front

What does the term 'GCF' stand for in algebra?

Back

GCF stands for 'Greatest Common Factor', which is the largest factor that divides two or more numbers.

Front

How do you factor an expression using GCF?

Back

To factor using GCF, identify the largest factor common to all terms, factor it out, and rewrite the expression.

Front

What is the vertex form of a quadratic equation?

Back

The vertex form of a quadratic equation is y = a(x - h)² + k, where (h, k) is the vertex of the parabola.

Front

How do you convert a quadratic equation from standard form to vertex form?

Back

To convert, complete the square on the quadratic expression.

Front

What is the cosine of an angle in a right triangle?

Back

The cosine of an angle A is defined as the ratio of the length of the adjacent side to the length of the hypotenuse: cos A = adjacent/hypotenuse.

Front

What is the tangent of an angle in a right triangle?

Back

The tangent of an angle C is defined as the ratio of the length of the opposite side to the length of the adjacent side: tan C = opposite/adjacent.

Front

What is the relationship between sine, cosine, and tangent?

Back

The relationship is given by tan A = sin A / cos A.

Front

How do you solve a system of equations graphically?

Back

To solve graphically, plot both equations on the same graph and identify the point(s) where they intersect.
