Distance between two points and
is given by the formula,
Distance =
a). A(-6, -4), B(-3, -1)
Distance between A and B =
=
= 3√2
= 4.2 units
b). C(3.5, 1), D(-4, 2.5)
Distance between C and D =
=
= 7.65
≈ 7.7 units
c). Distance between X(5, -5) and Y(-5, 5)
Distance =
=
= 10√2
= 14.14
≈ 14.1 units

Slope formula:
where (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate
Slope
In any right triangle ABC, with right angle A we have the following:
and
.
This means that the sine of a non 90° angle, is equal to the cosine of its complementary angle.
Thus,
