    rate of change = slope = \(\large \frac{y_2-y_1}{x_2-x_1}\) For each function, pick two points P1(x1,y1) and P2(x2,y2) and calculate the rate of change. That applies to #3 and #4. For one and two, you only have to transform the equations into the slope intercept form y=mx+b If m>0, then rate of change is positive, If m<0, then rate of change is negative. For example, Line is 2x-3y=-6 transform to 2x+6=3y or y=(2/3)x +2 so m=2/3 >0, and so rate of change is positive. You can do the same for both #1 and 2. If you wish, post your results for checking, together with work.
