 Hello : let  A(2,55)    B(4,91)<span>
the slope is :   (YB - YA)/(XB -XA)
(91-55)/(4-2)  = 36/2 =18
an equation is : y-55 = 18(x-2)</span>
<span> y-intercept when : x = 0  :  y - 55 = 18(0-2)
y-55 = -36
y = 55-36 = 19</span>
 
        
             
        
        
        
C. 20/4 because a fraction isn’t a whole number.
        
             
        
        
        
If you expand the square, you have

Simplify the right hand side:

Cancel the -3x appearing on both sides:

Multiply both sides by 4:

Consider the square root of both terms (using the doubles sign):
