This is the additive identity property or identity property of addition.
This property states that when you add 0 to a number, the result is the original number.
Someone getting all 20 problems correct would earn a grade of 100%. Thus, each correct question counts 5%.
If Emily earned 80%, then the number of problems she got correct was (80% / 100%).
Simplify this result. It represents the fraction of 20 questions that Emily got correct. Multiply your result by 20 to find the actual number of questions that E. got correct.
Hey there. So first we need to know what the point slope form looks like.
It is Y-Y1=M (X-X1)
Knowing this you just plug in the given information.
M is equal to 1/6. So in this case all of the options have the correct m. Next we look at the Year value. We know Y is a positive 4. So the beginning of the equation is going to look like
Y+4=1/6 ( X-X1).
Nown plug in x. It would be a negative 5. Now your final answer would be option A. Hope the explanation helped.. :)
