2.2 linear equations

Question 1

linear function

Answer 1

A function whose graph is a line.

Question 2

linear equation

Answer 2

two variables is an equation that can be written in the form ax+by=c.

Question 3

Dependent Variable

Answer 3

If a function is defined by an equation using the variables x and y, where y represents output values, then y is the dependent variable.

Question 4

Independent Variable

Answer 4

If a function is defined by an equation using the variables x and y, where x represents input values, then x is the independent variable.

Question 5

point- slope form

Answer 5

the point- slope form of an equation of a line y-y1=m (x-x1), where m is the slope of the line and (x1,y1) is a point of the line.

Question 6

x- intercept

Answer 6

The point at which a line crosses the x-axis is an x- intercept.

Question 7

Y- intercept

Answer 7

The point at which a line crosses the Y-axis is a Y-intercept.

Question 8

Standard form of a linear equation

Answer 8

the standard quiz of a linear equation is Ax+ By=C, where A, B, and C are real numbers, and A and B are not both zero.

Question 9

Slope

Answer 9

the slope of a non vertical line is the ratio of the vertical change to a corresponding horizontal change. the slope of a vertical line is undefined.

Question 10

Slope- intercept form

Answer 10

The slope- intercept form of an equation of a line is y=mx+b, where M is the slope and B is the Y-intercept.
