This is about Reasoning Strategy...
It says this:
3a. What is the y-intercept of the trend line?
3c. Write an equation for the trend line in slope-intercept form.
I don't really know what they mean?
Please help me.
3a. The y-intercept is where the line crosses the y axis. The y axis is the line going up and down. So if the line crossed at positive two your y-intercept would be +2.
3c. When they say write it in slope form they mean y=mx+b. M= slope b= y-intercept. Like if your slope went down 2 over 1 and your y-intercept was positive two your equation would look like this
Y = 2/1x + 2
I don't quite get 3c still?
whats y-intercept 4 and 5
Sure, I can help you with that!
When they say "trend line," they are referring to a line that represents the general direction or trend in a set of data points or values. It is also known as a line of best fit.
Now, let's break down the questions:
3a. What is the y-intercept of the trend line?
The y-intercept of a line is the point where it intersects or crosses the y-axis. In other words, it is the value of y when x is equal to 0. To find the y-intercept of the trend line, you need to know the equation of the line. The equation is usually in the form y = mx + b, where m represents the slope of the line, and b represents the y-intercept. So, in order to determine the y-intercept, you would need to know the equation of the trend line.
3c. Write an equation for the trend line in slope-intercept form.
The slope-intercept form of a linear equation is y = mx + b, where m represents the slope of the line, and b represents the y-intercept. To write the equation for the trend line in slope-intercept form, you need to know two things: the slope of the line and the y-intercept (b value).
To find the slope of the trend line, you would typically use the formula:
m = (change in y) / (change in x)
This involves selecting two points on the line and calculating the difference in their y-coordinates and x-coordinates.
Once you have the slope and the y-intercept, you can write the equation for the trend line using the slope-intercept form.
Overall, to answer questions 3a and 3c, you will need more information about the trend line, such as data points or the equation of the line. From there, you can determine the y-intercept and write the equation in slope-intercept form.
