Answer:

Explanation:

Observe what happens to y if we move from x = 1 to x = 9: y decreases by 2. Thus, the slope of the line in question is m = rise / run = -2/8, or -1/4.

Writing the equation in point-slope form, y - k = m(x - h), we get:

y - 7 = (-1/4)(x - 1) (point-slope form)

Solving for y results in the slope-intercept form:

y = 7 - x/4 + 1, or

y = (-1/4)x + 8 (slope-intercept form)
