MATH
if you look at a normal line equation it is y=mx+b the m is the slope/constant/first difference whatever you would like to call it. The b is the y intercept(where the line crosses the y axis). Therefore in your question 3x=2y+14 the slope (m) is 2 and the y intercept (b) is 14.

They are both the same. If you look at a line equation, y=mx+b the rate of change and slope is the m. If you are looking at a graph then to find the slope/rate of change you choos two points usually one after another and then see how many places horizontally (run) over to the ...
