8th Grade Math Mid Year Review

Front

What is the constant of proportionality in a graph?

Back

The constant of proportionality is the ratio of the dependent variable to the independent variable in a proportional relationship.

Front

Solve for c: 3 = c - 1

Back

c = 4

Front

What does the equation y = x + 2 represent?

Back

It represents a line with a slope of 1 and a y-intercept of 2.

Front

In slope-intercept form (y=mx+b), what do you graph first?

Back

You graph the y-intercept first and then use the slope to find the second point.

Front

Solve the equation: 0 = 4h

Back

h = 0

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over the run.

Front

What is the y-intercept in the equation y = mx + b?

Back

The y-intercept is the value of y when x = 0.

Front

What does it mean for two angles to be complementary?

Back

Two angles are complementary if the sum of their measures is 90 degrees.

Front

What is a one-step equation?

Back

A one-step equation is an equation that can be solved in a single step, typically involving addition, subtraction, multiplication, or division.

Front

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

Back

The slope is calculated using the formula: (y2 - y1) / (x2 - x1).
