could you please check this answer for me and correct. thanks
given equation point slope form linear equation to use to do question. y3 = 3(x+1)
question rewrite this equation in standard form
y 3 + 3 = 3x  3x +3 + 3
3x+ y = 6 collect all variables on one side and constants on other for standard form.
next question said, what is the x intercept of this line? would it be talking about 1 from original equation or 3x + y = 6
3x = y(0) = 6
x = 2 x inter is 2
thanks for your help. ann

3x + y = 6 is correct, but we usually start with a positive x term, so
3x  y = 6
for the xintercept, let y = 0 , (you are on the xaxis)
3x  0 = 6
x = 2
the xintercept is 2
yes, you were right.
