Answer:
false ignore this I needed to write something else to hand it in

<em><u>Solution:</u></em>
<em><u>Given that the expression is:</u></em>

We have to select the like terms
"Like terms" means that terms that has same variables with same exponent and same ( or different ) coefficients
In the given expression, y is a variable
Two terms has y as variable : 
Here variable "y" is same in both terms and coefficients are different
"x" is also a variable in given expression. But there are no other terms with "x" as variable
So they form a like terms

Thus the like terms are : 
The length of each shape will be an even number.
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
