Question 1 : find x intercept
y=0
0=3x+6
subtract 6 from both sides, after doing that, the equation would be : -6=3x
Then divide by -3 on both sides, the answer would be : x=3
Therefore the x intercept as a coordinate is (3,0)
Question 2 : find the y intercept
x=0
y=3(0)+6
y=6
Therefore the y intercept as a coordinate would be (0,6)
Hope this helped =)
