### How do you create a scatter plot on a TI-84 Plus?

### How do you graph on a TI-84?

The first step in any

**graphing**problem is to draw the**graph**. On the TI-83 and**TI-84**, this is done by going to the function screen by pressing the “Y=” button and entering the function into one of the lines. After the function has been entered, press the “**GRAPH**” button, and the calculator will draw the**graph**for you.### How do you create a data set on a TI-84?

### How do you find the equation of a table on a graphing calculator?

### How do you find the y value on a TI-84?

### How do you find the y value on a graph?

**Finding**the

**y value**is easy if you

**know the**slope of the line and the

**x**coordinate. Review the equation for the slope of a line. The equation for

**finding**the slope is: m = [y1 – y2] / [x1 – x2]. If you know

**x**, you can solve for

**y**to

**find**the

**y value**for the slope of the line.

### How do you plot a graph?

**Follow these simple steps:**

- First, find the value for x on the x-axis.
- Next, find the y-value – in this case, y=1100, so find 1100 on the y-axis.
- Your point should be plotted at the intersection of x=0 and y=1100.
- Finally,
**plot**the point on your**graph**at the appropriate spot.

**Steps**

- Step 1: For each (x,y) point
**calculate**x^{2}and xy. - Step 2: Sum all x, y, x
^{2}and xy, which gives us Σx, Σy, Σx^{2}and Σxy (Σ means “sum up”) - Step 3:
**Calculate Slope**m: - m = N Σ(xy) − Σx Σy N Σ(x
^{2}) − (Σx)^{2} - Step 4:
**Calculate**Intercept b: - b = Σy − m Σx N.
- Step 5: Assemble the
**equation**of a**line**.
