y = 20/3 x + 50
3 answers
The equation is in slope-intercept form, where the slope is 20/3 and the y-intercept is 50.
What would y = 20/3 x + 50 be as a scatter plot
To plot this equation as a scatter plot, you can choose different values for x, plug them into the equation, and calculate the corresponding values of y. Then, you can plot the pairs of x and y values on a graph. Here's an example:
Let's choose six values for x: -3, -1, 1, 3, 5, and 7. Then, we can calculate the corresponding values of y using the equation y = 20/3 x + 50:
- For x=-3, y=20/3*(-3)+50=40
- For x=-1, y=20/3*(-1)+50=46.67
- For x=1, y=20/3*1+50=53.33
- For x=3, y=20/3*3+50=60
- For x=5, y=20/3*5+50=66.67
- For x=7, y=20/3*7+50=73.33
Now we can plot the pairs of x and y values on a graph, as shown below:
```
|
80|
|
70|
|
60| ●
|
50| ● ●
|
40| ●
|
|--------------------------
-4 -2 0 2 4 6 8
```
Each dot(●) represents a point with an x value and a y value, as calculated above. By connecting the dots, we can see a line emerging, which represents the equation y = 20/3 x + 50.
