State Test Review 8th Grade Math

Front

What does a negative slope indicate in a scatter plot?

Back

A negative slope indicates that as the x-values increase, the y-values decrease.

Front

What is the equation of a line with a slope of -4?

Back

Front

What transformation maps triangle A onto triangle B if it involves a reflection over the x-axis followed by a translation?

Back

The transformation is a reflection over the x-axis, then a translation 6 units to the left.

Front

How do you determine the rate of change in a proportional relationship?

Back

Front

Back

The solution is the point (4, -2).

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, which can be proven through transformations.

Front

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

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of y when x = 0.

Front

How can you identify a proportional relationship from a graph?

Back

A proportional relationship can be identified by a straight line that passes through the origin (0,0).

Front

What is the formula for the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Front

What does a reflection over the y-axis do to the coordinates of a point (x, y)?

Back

A reflection over the y-axis changes the coordinates to (-x, y).
