how do you find x-intercept? in one question the y-intercept was (0,30) and the x-intercept was (-30,0) does that mean the x-intercept is always the opposite of the y-intercept?

you mean if you have straight line and you are trying to find it's interceptions with x-axis and y-axis? 
NO THEY ARE NOT OPPOSITE
line equation:
y=k*x+q
x-axis interception = -q/k
y-axis interception = q

and when y=0 what is x? this is how you find the x intercept
