Which of the following is the slope-intercept form of the equation?
The slope-intercept form of the equation is y = mx + b, where m represents the slope and b represents the y-intercept. It is used to graph linear equations easily.
How is the addition and subtraction equality used in linear equations?
in an equation like y=5x+3 the 3 would be the y-intercept
Graphing linear equation using the slope and y-intercept of the line?
The y-intercept, together with the slope of the line, can also be used in graphing linear equations. The slope and y-intercept of a line can be obtained easily by inspection if the equeation of the line is of the form y=mx+b where m is the slope and b is the y-intercept.
What are the three forms of a linear equation?
1. Slope-intercept form (most commonly used in graphing) y=mx+b m=slope b=y-intercept 2. Standard form ax+by=c 3. Point slope form (most commonly used for finding linear equations) y-y1=m(x-x1) m=slope one point on the graph must be (x1,y1)
How do you know if numbers show linear relationship?
A linear equation looks like any other equation. It is made up of two expressions set equal to each other. A linear equation is special because: It has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make the linear equation true and plot those pairs on a coordinate grid, all of the points for any one equation lie on the same line. Linear equations graph as straight lines.

Can linear equation not be rewritten in slope-intercept form?
A linear equation can be written in many different forms. Two forms are used frequently. ax+by=c is standard form as y=mx+b is slope intercept form.

What is the slope-intercept form of a line?
Slope-intercept form is one way of expressing a linear function (a fancy name for a straight line) as an equation.The slope-intercept form is modeled in the following way:y=mx+bwhere m represents the slope of the line and brepresents the y-intercept.Slope represents rate of change (how much y values change in relation to x) and on a graph determines how "sloped" a line is. Values of m close to 0 mean the line is more horizontal, or less sloped. As m approaches negative infinity or positive infinity, the line becomes more vertical, or more sloped.The y-intercept is simply the coordinate where the line crosses the y-axis on a Cartesian Plane. The point is (0, b).The slope-intercept method is popular because of its convenience. Using it, a graph of the line can be constructed very easily by hand without having to rearrange the equation. That said, in practical applications where computer software or graphing calculators are used, the form of a linear equation is less important. Slope-intercept form is often used by teachers and school textbooks.

What are the difference between linear equation and quadratic equation?
A linear equation is an equation that defines a relationship between variables, where each side of the equation consists of the sum of one or more terms, where each term must be one of: * A constant * A variable * A constant multiplied by a single variable All linear equations can be written as a first order polynomial equated to zero, but they may be written in many different forms. For example, the following are examples of linear equations, and the same equations written in its general form: * x = y + 5 >> x - y - 5 = 0 * 2x + 6y = 23 >> 2x + 6y - 23 = 0 * 5x + 3y = 4z - 20 >> 5x + 3y - 4z + 20 = 0 A linear equation with n variables defines a set of solutions in n-space, for example a linear equation with two variables defines a line in Cartesian (2D) coordinates, while one with three variables would define a plane in Euclidian (3D) coordinates. A linear equation with two variables defines a line in Cartesian coordinates, that is, if you graph the solutions to the equation on the x,y plane it will define a straight line. As you saw earlier, there are any number of ways that a linear equation may be written, but there are several recognized forms that are normally used. The one that most people are probably most familiar with is the "Slope-intercept" form, which looks like this: y = mx + b where: m is the slope of the line b is the y intercept of the line The shortcoming of this form is that it cannot define lines that are vertical, i.e. lines parallel to the y axis. Thus this form is only valid when y varies as a function of x. To allow the definition of any straight line, other forms must be used, such as: * General Form: Ax + By + C = 0 * Standard Form: Ax + By = C
When non-linear equation are graphed they do not have straight lines?
Not necessarily. It depends on the graph "paper" used. For example, you can get semi-log graph paper in which the x-axis is normal but the y-axis has a logarithmic scale. This feature is available on Excel in "format axis". On such a coordinate system, an exponential equation becomes a straight line.
