PART 1 8th Grade Unit 5 Assessment

Front

What type of solution does the system have if the lines are parallel?

Back

No solution.

Front

What does it mean if two lines intersect at one point?

Back

One solution.

Front

What is the solution of the system of equations: y = 5x - 4 and y = \frac{1}{2}x + 5?

Back

(2, 6)

Front

How can you determine if a system of equations has infinitely many solutions?

Back

If the equations represent the same line.

Front

What is the solution of the system of equations: y = \frac{1}{2}x + 1 and y = \frac{1}{2}x - 1?

Back

No solution (the lines are parallel).

Front

What does it mean if a system of equations has no solution?

Back

The lines are parallel and never intersect.

Front

What is the solution of the system of equations: y = 2x + 3 and y = -x + 1?

Back

(1, 5)

Front

How do you find the solution of a system of equations graphically?

Back

Plot both equations on a coordinate plane and identify the intersection point.

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the steepness and direction of the line.

Front

What does it mean if two lines are perpendicular?

Back

Their slopes are negative reciprocals of each other.
