8th Grade Math Midterm Review FALL 2024

Front

What is the first step to solve the equation 3x + 6 = 10 + 3x + 4x?

Back

Combine like terms 3x and 4x on the same side of the equation.

Front

Is the function linear or nonlinear?

Back

Nonlinear Function.

Front

Find the slope of the line represented by the equation y = 4x + 2.

Back

m = 4.

Front

What is the slope shown on the graph of the line that goes down 1 unit for every 2 units it goes to the right?

Back

m = -1/2.

Front

Does this mapping diagram represent a function if an input value goes to multiple output values?

Back

No, because an input value goes to multiple output values.

Front

What is the definition of a linear function?

Back

A function that graphs to a straight line and has a constant rate of change.

Front

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

Back

m = (y2 - y1) / (x2 - x1).

Front

What does it mean for a function to be one-to-one?

Back

Each input has a unique output, and no output is repeated.

Front

What is the y-intercept of the line represented by the equation y = 3x + 5?

Back

The y-intercept is 5.

Front

How do you determine if a relation is a function using a vertical line test?

Back

If a vertical line intersects the graph at more than one point, it is not a function.
