point: (-4, 5)

standard form: 7x - 3y = -43
ax + by = c
y - 5 = 7/3(x + 4)
y - 5 = (7/3)x + 28/3
y = (7/3)x + 28/3 + 5
y = (7/3)x + 28/3 + 15/3
y = (7/3)x + 43/3
(7/3)x - y + 43/3 = 0
(7/3)x - (3/3)y + 43/3 = 0
7x - 3y + 43 = 0(3)
7x - 3y + 43 = 0
7x - 3y = -43

x-intercept: (-6.14285714, 0)
7x - 3(0) = -43
7x = -43
x = -43/7
y = 0
