Line

Problem:



As far as I can read, it is $ y - 3 = \frac{3}{4}(x - 8) $

Solution:

The line is in point slope form, it passes through (8, 3) and has slope $ \frac{3}{4} $.

It can be written as $ 3x - 4y - 12 = 0 $, we can easily see it passes through (4, 0) and (0, -3)

Which mean the x-intercept and y-intercept are 4 and -3 respectively.
