First find the slope of the line.
\ (Substitute
for x1,
1 for y1,
for x2 and
for y2)
(Product of two same signs is positive)
(Add:
)
(Subtract:
)
(Multiply
, by reciprocal of
)
(Multiply:
)
Next find the y-intercept value by replacing m with , y with
and x with
in the equation
.
(Product of two different signs is negative)
Apply addition property of equality: If a = b then a c = b
c.
(Add
to each side)
Apply commutative property of addition: .
(Apply additive inverse proeprty:
)
(Add:
)
Replace m with and b with
in the slope-intercept form line equation
.
(Simplify)
The slope-intercept form line equation is .
