, simply a minor change from slope-intercept form, with slope and y-intercept (0,3). Graphable easily using the data.

, depends on how well you can understand standard form. Slope is , but you want at least one of the axis intercepts. Find either intercept you want. You CAN change the form to solve for one of them, unless you know something more efficient. Handling mentally, if x=0, then you can divide by , and this means y=-2; so the y-intercept is (0,-2). Use slope and y-intercept (0,-2) to plot the graph.

Done; no change in form used, except for a mental operation.
