Answer:

Explanation:

To find the equation of a line that passes through two given points, first find its slope by substituting the given points into the slope formula.
Define the points:
- (x₁, y₁) = (1, 7)
- (x₂, y₂) = (7, 5)
Substitute the points into the slope formula:

Therefore, the slope of the line is -¹/₃.

To find the equation in point-slope form, simply substitute the found slope and one of the given points into the point-slope formula:
