Given points are
Next, find the slope.
\Substitute 0 for y2, 2 for y1, 10 for x2, and 1 for x1 in slope formula.
\
(Product of two same signs is positive) \ \
(Add:
)
(Subtract:
) \ \
You know the slope and a point on the line, so use point - slope form
with either given point to write an equation of line.
\Choose
(Substitute 0 for y1, 10 for x1 and
)
(Apply additive identity property:
)
(Apply distributive property:
) \ \
(Multiply:
) \ \
The equation of line is .
