Q2 Review 8th grade

Front

If a system of equations has no solution, what does the graph look like?

Back

Parallel lines.

Front

Why do parallel lines never intersect?

Back

They have the same slopes.

Front

What is the solution to the system of equations represented by the point (4, -1)?

Back

(4, -1) is the solution.

Front

In the equation y = 3x - 4, what is the y-intercept?

Back

-4.

Front

Which equation matches the graph? y = 1/4 x + 2

Back

y = 1/4 x + 2.

Front

What is the slope of the line represented by the equation y = 2x + 3?

Back

The slope is 2.

Front

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

Back

The point where the line crosses the y-axis.

Front

How can you determine if two lines are parallel from their equations?

Back

If they have the same slope.

Front

What is the general form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What does it mean if two lines are skew?

Back

They are non-parallel lines that do not intersect and are in different planes.
