You cannot define a line with a single point (a single point only defines itself).
You need two points to define a line (and therefore to write the equation for it).
Slope Intercept form is meant for a line, so if you know the slope m in the equation y=mx+b then with a given point say (3,4) and say the slope of the line was 2 then the equation would read y=2x+4.
The slope of a curved line at a point is the slope of the tangent to the curve at that point. If you know the equation of the curve and the curve is well behaved, you can find the derivative of the equation of the curve. The value of the derivative, at the point in question, is the slope of the curved line at that point.
Assuming that the point is located at (1,1) then the equation is: y = -3x + 4 We know this by multiplying the slope by the x of the point given, and finding the difference between this value, and the y value of the point. 1 - (-3) is 4, hence the +4 in our equation.
There are a couple ways to determine the equation of a line without graphing. How to proceed depends on what you know about the line. Do you know a point, (x1, y1), and slope, m? Then use the point-slope formula, Do you know two points on the line, say (x1, y1) and (x2, y2)? Then use the two-point formula,
Substitute the first of the ordered pair wherever x appears in the equation and the second value wherever you have y. Evaluate the equation. If it is true, then the point is on the line and if not, it is not.
No, you need either two points, one point and a slope, one point and a y-intercept, or a y-intercept an a slope. You can also write the equation of a line with an equation of another line but you would have to know if it is parallel or perpendicular.

i dont know hahaha
the Equation of a Line Given That You Know Two Points it Passes Through.

that's simple an equation is settled of asymptotes so if you know the asymptotes... etc etc Need more help? write it
Umm nobody can answer this question because we don't know what "the scatter plot below" is.

You write down the main point so that your reader will know what it is. You also write it down so that you can be certain you have explained or supported the topic correctly.
x-25? you dont know the value of x there for you can only write out the equation
