Q2 Review 8th grade

Front

What is the y-intercept in the equation y = 3x - 4?

Back

The y-intercept is -4.

Front

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

Back

It means the lines are parallel and never intersect.

Front

What is the slope-intercept form of a linear equation?

Back

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

Front

What is the slope of the line represented by the equation y = 1/2x - 9?

Back

The slope is 1/2.

Front

How can you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope.

Front

What is the equation of a line with a slope of -3 and a y-intercept of -3?

Back

The equation is y = -3x - 3.

Front

What does it mean if a system of equations has infinite solutions?

Back

It means the lines are the same and overlap completely.

Front

How do you convert the equation 4x - 8y = 72 to slope-intercept form?

Back

Rearranging gives y = 1/2x - 9.

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 is the y-intercept of the line represented by the equation y = 4x + 2?

Back

The y-intercept is 2.
