Q2:
The point-slope form of an equation of a line:

m - slope
The formula of a slope:

We have the points (4, 6) and (6, 10). Substitute:

 <em>use distributive property</em>
           <em>use distributive property</em>
 <em>add 6 to both sides</em>
      <em>add 6 to both sides</em>
 <em>subteact 2 from both sides</em>
          <em>subteact 2 from both sides</em>

Q4:
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
Put the slope m = 3 and the coordinateso f the point (-2, 6) to the point-slope form of an equation of a line:

 <em>use distributive property</em>
         <em>use distributive property</em>
 <em>add 6 to both sides</em>
     <em>add 6 to both sides</em>

 
        
             
        
        
        
Answer:
10%
Step-by-step explanation:
Percent change= New-Old |Old|× 100% percent change=81-90 |90| × 100= -9 90×100=-10%

Alright, lets get started. 
space that is 7.0 cm long and 4.0 cm wide it means space is in rectangular shape.
The lenght of the space = 7 cm
The width of the shape = 4 cm
The formula of area of rectange = length * width
The area of rectange = 
The area of rectange = 28 square cm  
So, the area of the space you are aiming for 28 square cm.    :   Answer
