LINEAR EQUATIONS AND FUNCTIONS REVIEW

Front

What is the standard form of a linear equation?

Back

The standard form of a linear equation is written as Ax + By = C, where A, B, and C are integers, and A should be non-negative.

Front

Identify the y-intercept in the equation y = mx + b.

Back

The y-intercept is represented by the letter b, which is the value of y when x = 0.

What does it mean for a point to be a solution to an inequality?

Back

A point is a solution to an inequality if it satisfies the inequality when substituted into it.

Front

If y varies directly with x, what is the relationship between y and x?

Back

The relationship can be expressed as y = kx, where k is a constant of variation.

Front

Back

x = -rac{35}{12} or -2.92.

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

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

Back

The slope m is calculated as m = (y2 - y1) / (x2 - x1).

Front

What is the meaning of 'direct variation'?

Back

Direct variation means that as one variable increases, the other variable also increases at a constant rate.

Front

What is the x-intercept of a linear equation?

Back

The x-intercept is the value of x when y = 0.
