Question 1033047: what is the equation of a line with x intercept of 3 and a y intercept of -1

You can put this solution on YOUR website!
Intercepts are points, NOT scalar values. Saying "x-intercept of 3" is as ridiculous as saying a banana is an elephant. If 3 is the x-coordinate of the x-intercept and -1 is the y-coordinate of the y-intercept, then you have two ordered pairs that are on the graph of your line, namely (3,0) and (0,-1).
You also cannot find "the" equation of a line. For any given line there are infinite equations that represent that line. So, you can find "an" equation of a line, or the slope-intercept form of the equation of a line, or the standard form of the equation of a line, and so on.
If you are given two points use the Two-Point Form of an equation of a line:
(x\ -\ x_1) )
where ) and ) are the coordinates of the given points.
Plug in your coordinate values and do the indicated arithmetic. Then put it in whatever form you deem appropriate.
