Looking at the equation $2y=18$ , we see that if we want to isolate y, we need to divide it by 2 - because we're multiplying it by 2, and 2 times a number divided by 2 is just the number.

The Division Property of Equality states that if we have an equation, $a=b$ , then $a\div c = b\div c$ .

So, that means $2y\div 2$ will be equal to $18 \div 2$ , which is 9.

Hope this helped!

x = number of parties attended

y = number of text messages sent

The residual is the difference between the actual number of text messages sent (200) and the number of texts predicted by the regression model:

$y=64.96+25.41x\\y=64.96+25.41*3\\y=141.19$

The residual is:

$R=200 - 141.19\\R=58.81$
