Question 752766: I am super stuck on graphs, slopes, and linear equations. I am having trouble understanding exactly what an X - Y Function Table & Equation is. For example, i need to think of the pattern/function that will get me from x to y lets say usuing this equation, x is 7 and y is 14, i need to find the pattern/equation so how would i do that ? If you can explain very briefly please. Thank You .

Plot the x and y coordinate pairs on graph paper. Look for two pieces of numeric information from this graph.

Draw the best line you can to contain as many of the points as possible or to include the set of points as well as possible.
(*) Identify where the line intersects the y axis. This is the y-intercept. Call this number, b.
(*) Compute the ratio of the vertical change to the horizontal change as you move from left to right on the line; this is the slope. Call this number, m.

Your function is y=%28m%29%2Ax%2B%28b%29.
