<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 5(2 - x)
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]:                                                                           f(-1) = 5(2 - -1)
- (Parenthesis) Subtract:                                                                                     f(-1) = 5(3)
- Multiply:                                                                                                             f(-1) = 15
 
        
                    
             
        
        
        
Answer:
3.11
Step-by-step explanation:
[(3.5)(2) + (3)(3+4)] ÷ 9
(7 + 21)/9 = 28/9

We have been given that a line  passes through the point (10, 3) and is parallel to the line
 passes through the point (10, 3) and is parallel to the line  . We are asked to find the y-intercept of the line.
. We are asked to find the y-intercept of the line.
First of all we will rewrite our given equation in slope-intercept form as:




We know that slope of parallel lines is equal, so slope of parallel line to our given line would be  .
.
Now we will use slope-intercept form of equation to find y-intercept.
  , where,
, where,
m = Slope,
b = The y-intercept.
Let us substitute  and coordinates of point
 and coordinates of point  in above equation as:
 in above equation as:





Therefore, the y-intercept is 7 and our required equation would be  .
.
