Answer:
The simplified expression for the given expression will be:
c. 
Step-by-step explanation:
Given expression:

To simplify the expression.
Solution:
In order to simplify the expression, we will first remove the parenthesis by reversing the signs of the terms inside the parenthesis which lies after a negative sign out side the parenthesis.
<em>This is because negative multiplies to a negative to give a positive and negative multiplies to a positive to give a negative.</em>
So, we have:
⇒ 
Combining like terms
⇒ 
<em>The like terms can be evaluated as</em>


Thus, the simplified expression will be:
⇒ 
Answer:
5 is the answer
Step-by-step explanation:
because it you add 5 to all the x values you get the y values
The y intercept of a graph containing the two points (3,1) and (7,-2) is 
<em><u>Solution:</u></em>
Given points are (3, 1) and (7, -2)
<em><u>The equation of line in slope intercept form is given as:</u></em>
y = mx + c ------- eqn 1
Where, "m" is the slope of line and "c" is the y intercept
<em><u>Let us first find the slope of line</u></em>
The slope of line is given as:

Here the points are (3, 1) and (7, -2)

Substituting in formula, we get

To find the y intercept:


Thus y -intercept is
