Slope is equal to the change in
y
y
over the change in
x
x
, or rise over run.
The change in
x
x
is equal to the difference in x-coordinates (also called run), and the change in
y
y
is equal to the difference in y-coordinates (also called rise).
Substitute in the values of
x
x
and
y
y
into the equation to find the slope.

Hi there!
Th' following triangle is divided into 2 sub-triangles!
• In 1ˢᵗ triangle :-
tan 45° =

⇒ 1 =

⇒

= 5
• In 2ⁿᵈ triangle :-
cos 30° =

⇒

=

⇒

= 2 × 5
⇒

= 10
Hence,
Th required answer is 10 units.
~ Hope it helps!
