What is the equation through the origin and (7, 2)?

See the entire solution process below:
Explanation:
The origin is the point
(
0
,
0
)
We can use the point-slope formula to find the equation of the line passing through the origin and having a slope of 3. The point-slope formula states:
(
y
−
y
1
)
=
m
(
x
−
x
1
)
Where
m
is the slope and
(
x
1
y
1
)
is a point the line passes through.
Substituting the slope and point from the problem gives:
(
y
−
0
)
=
3
(
x
−
0
)
y
=
3
x
i don’t know this answer but i hope this helped
