Slope of a line = (change in y)/(change in x). So for the change in y, subtract the y-coordinate of one point from the y-coordinate of the other point. For the change in x, do the same thing with the x-coordinates. It doesn’t matter which point you start with, but you *have* to start with the *same* point both times (calculating change in y and then calculating change in x).

Once you have the slope of your line (hint: it will be a negative fraction that you can reduce to a denominator of 5), remember that y = mx + b gives you a formula for finding all the points that fall on a particular line. So that means either one of your points will “solve” the equation y = mx + b, since they are both on the line. Pick *one* of your two points and plug it into the y = mx + b equation. You know x and y (they are the coordinates of whichever point you chose), and you know the slope m because you just calculated it. You can solve for your one unknown, the y-intercept b.

Once you have m and b, you know the slope-intercept form of the equation. To check that you did it right, do the whole thing again, using the *other* point first when doing the slope calculations, and then finding b using the point you didn’t use the first time. Both methods will give you the same answer.

As for graphing using a table, your answer of (1, 22 2/7) is right. Plug in values for x and calculate the output values of y. Then take those pairs of numbers (the x you put in and the y you got out) and plot them as points on a grid. Connect the points in a line to finish your task of graphing with a table.
