help plzzzz !!!!!!!!!!! BRAINLY AND POINTS

Answer:
y =3x
Step-by-step explanation:
The y intercept is 0, because it goes thru the origin
(0,0)
To find the slope , we need two points
We have (0,0) and (1,3)
m = (y2-y1)/ (x2-x1)
= (3-0)/(1-0)
=3/1
The slope is 3
The equation for a line is y=mx+b where m is the slope and b is the y intercept
y = 3x+0
y =3x
Answer:
y=3x
Step-by-step explanation:
Slope using points (0,0) and (1,3)
(3-0)/(1-0)=3/1=3
slope is 3, y intercept is (0,0), so the equation of the line is y=3x+0, or y=3x
