What is the equation of a line in slope-intercept form?

Back

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

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What does it mean if two lines are parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is 180°.

Front

How many triangles can be formed from a hexagon?

Back

A hexagon can be divided into 4 triangles.

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed. It can be written in the form y = mx + b.

Front

What does it mean for an equation to have no solution?

Back

An equation has no solution if it leads to a false statement, such as 4 = 7.

Front

What is the relationship between the coefficients in the equation ax + b = a(x + c)?

Back

For the equation to hold true, c must equal b/a.
