I don’t know how to do slopes. Can someone help me?

Slope is rise over run. so, if you have a line of best fit, you go from one point to the next. Up 1 would be 1 down one would be -1. right 1 would also be 1, left one is -1. After you get the rise over run (Say it's 5/4) then you divide rise over run. 1.25 is the slope of this one.  post this question with a picture of a graph and i'll gladly help

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
