Question

Complete the equation of the line whose y-intercept is (0,6) and slope is 3.

Answer 1

(y-y1)=m(x-x1)
y-6=3(x-0)
y-6=3x-0
Add 6 to both sides
y=3x+6
This is the equation of the line

Answer 2

The equation of line is y=3x+6

Explanation:

Given: A line passed through (0,6) and slope is 3

Using slope intercept form:

y=mx+b

where, m is slope and b is y-intercept

m=3

y=3x+b

y-intercept: (0,6) i,e b=6

y=3x+6

Hence, The equation of line is y=3x+6
