Answer 1

To find the equation of the line in point-slope form, we first need to determine the slope of the line using the two points (8, 10) and (13, 17).

The formula for the slope \( m \) between two points \((x_1, y_1)\) and \((x_2, y_2)\) is:

\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]

Substituting in the given points:

• \( (x_1, y_1) = (8, 10) \)
• \( (x_2, y_2) = (13, 17) \)

We have:

\[ m = \frac{17 - 10}{13 - 8} = \frac{7}{5} \]

Now that we have the slope \( m = \frac{7}{5} \), we can use the point-slope form of a line equation, which is:

\[ y - y_1 = m(x - x_1) \]

Using the point (8, 10):

\[ y - 10 = \frac{7}{5}(x - 8) \]

Thus, the equation of the line in point-slope form is:

\[ \boxed{y - 10 = \frac{7}{5}(x - 8)} \]

So the correct answer is:

y−10=75(x−8)
