Answer:
D. All real numbers are either rational or irrational.
9 because 16 plus 9 is 25 and 21 plus 9 is 30. now you have 25/30
Now you have to simplify:
25 divided 5 is 5 and 30 divided 5 is 6. So 5/6
QUESTION
Your equation is 2x+3y=2 and you need to find the slope.
EXPLANATION
There are many ways to find the slope with an equation like this. I'm going to change the equation into slope-intercept form.
Slope-intercept form is formatted like this:
y=mx+b
m represents the slope. The first thing you need to do is leave 3y alone to change the equation into slope-intercept form. That means you need to subtract 2x from both sides.

The next thing you need to do is leave y alone, just like the slope-intercept form example. To leave y alone, you need to divide 3y by 3.

Now the equation has been changed to slope-intercept form. In the equation, m has been replaced by
, which means that is your answer.
