I have a few question so I will number them off. Please answer them for me I have a test tommorow and I am sure this can help other people too.
1.How do you make an equation that passes through a yintercept and a certain point in slopeintercept form.
2.How do you find the slope and
yintercept of a horizontal or vertical line.(It is 0 and unidentified right, but which one is which?)
3.How do you write an equation in point slope form that passes through a certain point and has a certain slope.
4.How do you find a parallel equation with an equation in slopeintercept form and it has to pass through a certain point.
Thank you for answering my questions if you did take the time. It would be much appreciated for my test tomorow
