Yo, what’s up? Let’s talk about T-charts and the slope formula. 🤙

So, first things first, the slope formula is used to calculate the slope of a line. The slope of a line is basically how steep it is, and it’s calculated by dividing the change in the y-coordinates by the change in the x-coordinates between two points on the line. The formula for slope is:

slope = (y2 – y1) / (x2 – x1)

Now, let’s talk about T-charts. A T-chart is a table used to organize data. It’s called a T-chart because it looks like a T. On the left side of the T, you write the x-values and on the right side of the T, you write the corresponding y-values.

To use the slope formula with a T-chart, you need to choose two points on the line and plug their coordinates into the formula. For example, let’s say we have the following T-chart:

x y

1 3

2 5

3 7

To find the slope of the line that passes through these points, we need to choose two of the points and plug their coordinates into the slope formula. Let’s choose the first two points:

slope = (5 – 3) / (2 – 1)

slope = 2 / 1

slope = 2

So, the slope of the line that passes through the first two points is 2. 😎

Now let’s choose the second and third points:

slope = (7 – 5) / (3 – 2)

slope = 2 / 1

slope = 2

So, the slope of the line that passes through the second two points is also 2. 😅

Hope that helps! Hit me up if you have any more questions. 🤗
