Graph the equation

How do you graph an equation?

To graph a linear equation, we can use the slope and y-intercept.Locate the y-intercept on the graph and plot the point.From this point, use the slope to find a second point and plot it.Draw the line that connects the two points.

How do you calculate on a graph?

Using the Slope EquationPick two points on the line and determine their coordinates.Determine the difference in y-coordinates of these two points (rise).Determine the difference in x-coordinates for these two points (run).Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).

How do you graph a slope equation?

Graphing a Linear Equation Using Slope Intercept Formy = mx + b.Graph the equation: y = 2x + 4.Slope = 2 or 2/1.Y-intercept = 4 or (0,4)Step 1: Plot the y-intercept on your graph. Step 2: From the y-intercept (0,4) use the slope to plot your next point.The slope is 2, so you will rise 2 (up) and run 1 (to the right).

How do you write an equation of a line?

The slope-intercept form of a linear equation is written as y = mx + b, where m is the slope and b is the value of y at the y-intercept, which can be written as (0, b). When you know the slope and the y-intercept of a line you can use the slope-intercept form to immediately write the equation of that line.

What is slope of a graph?

The steepness of a hill is called a slope. The same goes for the steepness of a line. The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.

How do you find the rise and run on a graph?

See what you get.) The formula for slope is sometimes referred to as “rise over run”, because the fraction onsists of the “rise” (being the change in y, going up or down) divided by the “run” (being the change in x, going from left to the right).

What are the 3 ways to graph a linear equation?

There are three basic methods of graphing linear functions. The first is by plotting points and then drawing a line through the points. The second is by using the y-intercept and slope. The third is applying transformations to the identity function f(x)=x f ( x ) = x .

Depreciation equation

What are the 3 depreciation methods? There are three methods for depreciation: straight line, declining balance, sum-of-the-years’ digits, and units of production. What do you mean by depreciation? Definition: The monetary value of an asset decreases over time due to use, wear and tear or obsolescence. This decrease is measured as depreciation. How do you […]
