Answer:


y=3x+6

Explanation:

Hi there!

Slope-intercept form:
y=mx+b where m is the slope and b is the y-intercept (the value of y when x=0)

We're given that the slope of the line is 3. Plug this into
y=mx+b as m:


y=3x+b

We're also given the point (0,6). Since the y-intercept occurs when x=0, the y-intercept is therefore 6. Plug this into
y=3x+b as b:


y=3x+6

I hope this helps!
