Limited Number of Attempts:
Find the slope and the y-intercept of the line. This example is written in function notation, but is still linear.
As shown above, you can still read off the slope and intercept from this way of writing it. We can get down to business and answer our question of what are the slope and y-intercept. In this form, the slope is m, which is the number in front of x. In our problem, that would have to be 2. In this form, the y-intercept is b, which is the constant.
In our problem, that would be The answer is the slope is 2 and the y-intercept is Note how we do not have a y.
This type of linear equation was shown in Tutorial If you said vertical, you are correct. The graph would look like this: Note that all the x values on this graph are 5.
Well you know that having a 0 in the denominator is a big no, no. This means the slope is undefined.
As shown above, whenever you have a vertical line your slope is undefined. Looking at the graph, you can see that this graph never crosses the y-axis, therefore there is no y-intercept either. Another way to look at this is the x value has to be 0 when looking for the y-intercept and in this problem x is always 5.
So, for all our efforts on this problem, we find that the slope is undefined and the y-intercept does not exist.Write the equation for a line that has a slope of -2 and y-intercept of 5. NOTES: I substituted the value for the slope (-2) for m and the value for the y-intercept (5) for b.
The variables x and y should always remain variables when writing a linear equation. By watching this simple tutorial you can easily compute the Y-intercept of an equation in point slope form. How To: Write a slope-intercept equation given an X-Y table How To: Use and find x & y-intercepts in algebra.
Steps For Writing Equations Given Two Points. Use the slope formula to find the slope.; Use the slope (that you found in the step above) and one of the points to find the y-intercept. (Using y = mx+b, substitute x, y, and the slope (m) and solve the equation for b.).
Aug 23, · Best Answer: The equation for a standard line is y = mx+c. Here you have two points through which the line passes.
(x intercept & y intercept). Thus you can form two equations by substituting the value of your r-bridal.com: Resolved. In mathematics, a polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.
An example of a polynomial of a single indeterminate, x, is x 2 − 4x + r-bridal.com example in three variables is x 3 + 2xyz 2 − yz + 1.
You can put this solution on YOUR website! How do you write an equation in slope-intercept form when given the x and y-intercepts? Example: x-intercept 3, MEANS VALUE OF X=3 WHEN Y=0 THAT IS (3,0)IS A POINT ON THE LINE.
