Answer:
y =  x + 7
 x + 7
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
here m =  , hence
, hence
y =  x + c ← is the partial equation
 x + c ← is the partial equation
to find c substitute (4, 9) into the partial equation
9 = 2 + c ⇒ c = 9 - 2 = 7
y =  x + 7 ← equation in slope-intercept form
 x + 7 ← equation in slope-intercept form
 
        
             
        
        
        
Answer:

Step-by-step explanation:
The slope-intercept form of an equation of a line:

<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:

We have the points (5, -5) and (-4, -2).
Substiute:

Put the value of the slope and the coordinates of the point (5, -5) to the equation of a line:

 <em>add 5/3 to both sides</em>
               <em>add 5/3 to both sides</em>

Finally we have the equation of a line in the slope-intercept form:

Convert to the standard form <em>(Ax + By = C)</em>:
 <em>multiply both sides by 3</em>
          <em>multiply both sides by 3</em>
 <em>add x to both sides</em>
              <em>add x to both sides</em>

If you're factoring, your answer is 
(4x - 3)(4x + 5) 
You'll work it out this way:
16x^2 + 8x - 15
Since there's no GCF here, you multiply the first and third terms, giving you -240. Your next step is to find two numbers that have a sum of 8 and a product of -240. These numbers are 20 and -12. Plug those in and you've got:
16x^2 + 20x - 12x - 15
From here you divide it into two binomials. These are (16x^2 + 20x) and (-12x - 15).
When you take out the greatest common factors (4x and -3), they become:
4x(4x + 5) - 3(4x + 5)
Then you group what's outside of the parentheses together (4x - 3)
And bring what's inside of the parentheses down (4x + 5).
This brings your answer to 
(4x - 3)(4x + 5)
