On a TI-84, if I have 4 points and I know how to graph the points but then how do I find an equation of the?

Question

line? Do I use slope intercept form?

Answer 1

I am not familiar with the TI-84. But if you want to find the equation of a line without the use of a calculator or computer, you would use the the slope intercept form. Next, let x equal zero to find the y intercept for, y=mx+b, where m is the slope and b is the y-intercept.

Good luck!!
