ok i have an equation and a line drawn out and i need to use the line to check the equation

It depends on what you mean by "check". If you have a couple of points that are on the line, you can check it by plugging those points in and seeing if it works. If you have conditions (like "slope of 3, passing through the point (1, 2)), you can check the conditions (in this case the slope, and it should be obvious if you have the right slope) and any points you've been given.
If you have some other type of information, then you'll have to tell me what it is before I can help you.

Your answer is authentic. If the slope is undefined, it means you've a vertical line. Vertical lines do not extremely in good structure into the slope-intercept form because (a) they don't have any slope and (b) they frequently don't have any y-intercept. the variety for equations of vertical lines is x = ok, the position ok is a continuing.

you can subsitue corrdinates from you line to make sure they are equal. i.e. y=mx+b, you can plug in x from any coordinate on the line (3,4) (1,6) etc... what ever they may be make sure that when the x value is multiplied by slope, (rise over run) plus the y intercept will equal the y value.

y=mx+a
