Which best describes the effect on the graph of y equals 4x plus 8 if the y-intercept is changed to -3?

If you were to graph both equations side by side, you would see that they are parallel lines. Both equations have the same slope it is just that the line would be moved down in the graph because of the intercept change.

I had unprotected sex 10 days before my period was supposed to start my period ended up being 10 days late could i be pregnant?

Yes, It is possible, I was told by my mother, that you can ovalate, seven day's before your cycle or seven day's after. You only ovalate on one day, but, who knows which day out of 14 days? I lived by this. I have only two children, which I had, by NOT following her rule. I had no children when I followed the Rule she gave me. I see that you did start, but was three day's late! You maybe alright, then!! Usually, women don't have periods, after they concieve. Although, their have been some cases that I have been told that they did have a few periods even thought they were pregnant. But, that's only some. Just wait until after your period and take a pregnancy test. Try not to worry though, worry can cause our periods to mess up, which causes more worry. Wish you well!!
