This one really threw me off...
find the slope of the line containing the points
(x, 2x) and (x + h, 2(x +h))
You have to first find the slope, which is change in y over change in x:
{[2(x-h)]-2x}/[(x+h)-x]
(2x-2h-2x)/(x+h-x)
-2h/h
m=-2.
i don't have an anwser but i need help with my algebra graphing problems i don't know how anything works and i don't have a lot of time but i just need to know how to find a t chart and solve the equation for y-2x=-2 so please and yeah if it takes 24 hours online homework help sucks hard
Well, I'm kind of confused by your question, but to get a t-chart, hit "STAT". Then hit "Edit". L1 are your x-values and L2 are your y-values. To graph y-2x=-2, first rearrange the equation to y alone:
y=2x-2. Then press the "Y=" button on your calculator and type it in. Then press "Graph".
To solve the equation y-2x=-2, you can use a t-chart to find the values of y for different values of x.
First, rearrange the equation to solve for y:
y = 2x - 2
Now you can create a t-chart. Start by choosing some values of x and plugging them into the equation to find the corresponding values of y.
For example, let's choose x = 0:
y = 2(0) - 2
y = -2
For x = 1:
y = 2(1) - 2
y = 0
You can continue this process for other values of x. Once you have a few values of x and their corresponding values of y, you can plot them on a graph to visualize the equation.
Now, to use your calculator to create a t-chart and graph the equation, follow these steps:
1. Press the "STAT" button.
2. Select "Edit" to enter the data into the lists.
3. Choose a list for your x-values, such as L1, and enter the values.
4. Choose a list for your y-values, such as L2, and enter the values computed using the equation y = 2x - 2.
5. Press the "Y=" button on your calculator to access the equation editor.
6. Enter the equation y = 2x - 2.
7. Press the "GRAPH" button to plot the equation on the graph.
By following these steps, you should see the graph of the equation y-2x=-2, allowing you to visualize the relationship between x and y values and identify points on the graph.
