The tram could cover 400 centimeters in 50 seconds. if the rate of the tram were reduced by one half during the thunderstorm< how far could the tram go in 2 seconds?

Can someone me with the property questions for 12 13 and 14 plz

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.

Astudent draws two parabolas both parabolas cross the x axis at (-4,0) and (6,0) the y intercept of the first parabolas is (0,-12). the y intercept of the second parabola is (0,-24) what is the positive difference between the a values for the two functions that describe the parabolas
