I can't tell her if the answers or if she is doing them is the correct way.

In all three of these lines, every 1-unit change in y is associated with a 1-unit change in x. Introduction Straight lines are produced by linear functions. To find the rate at which y is changing with respect to the change in x, write your results as a ratio: A function which satisfies these properties is called a linear functionor more generally a http: Therefore the slope of this line is 2.

Subtract 2x from both sides to get: And of course, if you need more help, feel free to ask the volunteers on our math help message board. These lines have undefined slope. The coefficients may be considered as parameters of the equation, and may be stated as arbitrary expressionsrestricted to not contain any of the variables.

Standard Form of a Line by: The standard form can be converted to the general form, but not always to all the other forms if A or B is zero. This form is also called the Hesse standard form, after the German mathematician http: The terms in an expression are separated by addition or subtraction symbols.

Again, start by moving the x-term to the left. The variables x and y should always remain variables when writing a linear equation. Changing the value of b moved the line around the coordinate plane.

The original equation, therefore, would be called an http: Slope-intercept form where m is the slope of the line and b is the y -intercept, which is the y -coordinate of the point where the line crosses the y axis.

General form of standard form and the equation of the line in standard form? To find a value for y given a value for x, substitute the value for x into the expression and compute. Vertical lines, having undefined slope, cannot be represented by this form. We need the x-term to be positive, so multiply the equation by -1 to get our answer: This means that a positive change in y is associated with a positive change in x.

Note that all the x values on this graph are 5. B It is represented by m. There are two ways to put it in slope-intercept form. The steeper the slope, the greater the rate of change in y in relation to the change in x. So if you could please tell me the answer and how you got it that would be great!

Point-Slope Calculator Many functions to try! Locate another point that lies on the line. Write an equation in slope intercept form given the slope and y-intercept.

To find ordered pairs of solutions for such an equation, choose a value for x, and compute to find the corresponding value for y.A line whose slope is undefined has no finite slope; the line is a vertical one. A vertical line has an equation of the form x = k.

In this case, since the line passes thru (-6,4), the eq'n of the line is x = Write a slope-intercept equation for the line whose graph is described. a) Parallel to the graph of 4x 5y = 3, with y-intercept (0, 5).

b) Perpendicular to the graph of 4x 5y = 3,bistroriviere.com Example 7: Find an equation for the line through the point (-1, 3) and parallel to the line whose equation is 0 5 2 3 =--y x.
