Solving Systems by graphing

Front

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

Back

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

What does the y-intercept represent in the slope-intercept form?

Back

The y-intercept (b) represents the point where the line crosses the y-axis.

Front

What does it mean if two lines are parallel in a system of equations?

Back

If two lines are parallel, it means they have the same slope but different y-intercepts, indicating that the system has no solution.

Front

How can you determine if a point (x,y) is a solution to a system of equations?

Back

A point (x,y) is a solution if it satisfies both equations in the system.

Front

What is the graphical representation of a system of equations with one solution?

Back

The graphical representation shows two lines intersecting at a single point.

How do you convert the standard form of a linear equation to slope-intercept form?

Back

To convert from standard form Ax + By = C to slope-intercept form, solve for y to get y = (-A/B)x + (C/B).

Front

What does it indicate if a system of equations has infinitely many solutions?

Back

It indicates that the two equations represent the same line, meaning they overlap completely.

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

Back

The coefficients determine the slope and the position of the line in the coordinate plane.
