Unit 3 & 4 Finals Review - EL IAG

Front

What is the equation of a line with a slope of 1/3 and a y-intercept of -2?

Back

y = 1/3x - 2

Front

What postulate states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent?

Front

Which triangle congruence theorem states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent?

Back

SAS (Side-Angle-Side) Theorem

Front

Back

-\frac{3}{2}

Front

Define slope in the context of a linear equation.

Back

Slope is the measure of the steepness of a line, calculated as the change in y over the change in x.

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis.

Front

What is the formula for finding the slope between two points (x1, y1) and (x2, y2)?

Back

Slope = \frac{y2 - y1}{x2 - x1}.

Front

What does the SAS postulate stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side.

Front

What is the significance of the y-intercept in the equation of a line?

Back

It indicates the value of y when x is 0.
