The equation that represents the situation, in point-slope form, is: [tex]\mathbf{y - 65 = 8(x - 5)}[/tex]

Recall:

If we know the slope and a point (a pair of values), a linear equation can be written in the point-slope form as: [tex]y - y_1 = m(x - x_1)[/tex].

In [tex]y - y_1 = m(x - x_1)[/tex], m = slope; [tex](x_1, y_1)[/tex] = a point or pair of values on a table.

Using two points or pairs of values, [tex]slope = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Thus, we are given the table as shown below (see attachment).

The slope, using (3, 49) and (5, 65) is calculated below:

[tex]slope = \frac{65 - 49}{5 - 3} = \frac{16}{2} \\\\\mathbf{slope (m) = 8}[/tex]

To write the equation in point-slope form, substitute [tex](x_1, y_1)[/tex] = (5, 65) and m = 8 into [tex]y - y_1 = m(x - x_1)[/tex].

Thus:

[tex]\mathbf{y - 65 = 8(x - 5)}[/tex]
