The line equation in slope-intercept form is
, where m is the slope and b is the y-intercept.
First find the slope (m).
\Slope formulae is 
(Replace
with -2, 5, 3 and 1)
(Subtract:
)
(Add:
)
Slope is 
Next find the y-intercept (b).
\
(Substitute
for m)
(Substitute 3, 1 for x, y)
(Multiply:
)
(Add
to each side)
(Apply Commutative property:
