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

Back

The point-slope form of a linear equation is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

How do you find the slope from an equation in slope-intercept form?

Back

In the slope-intercept form y = mx + b, the slope (m) is the coefficient of x.

What does the inequality k < 3 represent on a number line?

Back

The inequality k < 3 represents all values of k that are less than 3, which is shown as an open circle at 3 and a line extending to the left.

How do you solve the equation 96 = -3(4x - 4)?

Back

To solve, first distribute: 96 = -12x + 12. Then, isolate x: 12x = 12 - 96, so x = -7.

What is the solution to the equation -8 - 5a = 12 - 9a?

Back

To solve, first add 9a to both sides: -8 + 4a = 12. Then, add 8 to both sides: 4a = 20, so a = 5.

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

Back

The slope indicates the steepness of the line and the direction of the relationship between the variables; a positive slope means the line rises, while a negative slope means it falls.

What is the difference between a linear equation and an inequality?

Back

A linear equation represents a straight line, while an inequality shows a range of values that satisfy a condition, often represented with a shaded region on a graph.

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

Back

To convert from standard form Ax + By = C to slope-intercept form y = mx + b, solve for y in terms of x.

What does it mean for a line to be parallel to another line?

Back

Two lines are parallel if they have the same slope but different y-intercepts, meaning they will never intersect.

What is the formula for calculating the slope between two points (x1, y1) and (x2, y2)?

Back

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