y = (7/5)x - 1 has a slope of 7/5.
The line we need is parallel to it, so the line we need must also have slope 7/5.
Using the slope formula, we have:
(y - 5) / (x - 2) = 7/5
(y - 5) = (7/5)(x - 2)
y - 5 = (7/5)x - (14/5)
y = (7/5)x - (14/5) + 5
y = (7/5)x - (11/5), which is the slope-intercept form of the line we need.
