Systems of Equations Graphing Practice 11/6 and 11/7

Front

The solution (x, y) to a system of equations is the point where they...?

Back

Intersect

Front

When graphing lines, we ALWAYS start on the _____________

Back

y-axis

Front

What is the solution to the system? (3, -1), (2, -6), No Solution, (6, -2)

Back

(6, -2)

Front

If there is no constant (number at the end), where do we start?

Back

Right in the middle (origin)

Front

What is the solution to this system? (1, -1), (-1, 1), (0, -2), (2, 0)

Back

(1, -1)

Front

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

Back

They have no solution because they never intersect.

Front

What is the slope-intercept form of a line?

Back

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

Front

How do you find the y-intercept of a line from its equation?

Back

Set x = 0 and solve for y.

Front

What is the graphical representation of a system of equations?

Back

It is represented by the intersection points of the lines on a graph.

Front

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

Back

The equations represent the same line.
