To find the slope of the line that passes through two points, you can use the slope formula:
Slope (m) = (y2 – y1) / (x2 – x1)
In this case, we have two points: (1, 2) and (3, 8). Let’s identify the coordinates:
- (x1, y1) = (1, 2)
- (x2, y2) = (3, 8)
Now, substituting these values into the slope formula:
m = (8 – 2) / (3 – 1)
Calculating it step by step:
- Subtract the y-coordinates: 8 – 2 = 6
- Subtract the x-coordinates: 3 – 1 = 2
Now plug these results back into the formula:
m = 6 / 2
This simplifies to:
m = 3
So, the slope of the line that passes through the points (1, 2) and (3, 8) is 3.
