2.2: Linear Equations

Question 1

Linear Function

Answer 1

A function whose graph is a line.

Question 2

Linear Equation

Answer 2

You can represent a linear function with a —–. A solution of a —– is any ordered pair that makes the equation true.

Question 3

Dependent Variable

Answer 3

Because the value of y depends on the value of x, y is called the —–.

Question 4

Independent Variable

Answer 4

The x value is the —–

Question 5

Y-intercept

Answer 5

The —– of a line is the point at which the line crosses the y-axis.

Question 6

X-intercept

Answer 6

The —– of a line is the point at which the line crosses the x-axis.

Question 7

Standard Form of a Linear Equation

Answer 7

Is Ax + By = C, where A,B, and C are real numbers, and A and B are both not zero.

Question 8

Slope

Answer 8

The —– of a non-vertical line is the ration of the vertical change to a corresponding horizontal change.

Question 9

Point-Slope Form

Answer 9

When you know the slope and a point on a line, you can use the —– to write the equation of the line.

Question 10

Slope-Intercept Form

Answer 10

Another form of the equation of a line is —–, which you can use to find slope by examining the equation.
