For this case we have the following equation:

y = 7x + 3

To find the y-intersection values we do
x = 0 :

$y = 7 (0) +3\\y = 0 + 3\\y = 3$

To find the x-intersection values we do
y = 0

0 = 7x + 3

Subtracting 3 on both sides:

-3 = 7x

Dividing between 7 on both sides:

$x = - \frac {3} {7}$

So, we have:

x-intersection:
$(- \frac {3} {7}, 0)$

y-intersection:
(0,3)
