First, we'll find the slope of the new line. The first line has a slope of  . Take the negative reciprocal of this (Flip the numerator and denominator, then multiply by
. Take the negative reciprocal of this (Flip the numerator and denominator, then multiply by  ) to get
) to get  for the new slope.
 for the new slope.
Then, we'll use the point-slope form to make the new equation, where  is the slope and
 is the slope and  is a point on the line:

Answer:
Step-by-step explanation:
46+x=77 subtract 46 from both sides
x=31
 
        
             
        
        
        
Answer:
x=6 y=-9
Step-by-step explanation:
- Layer the equations on each other as you would in a subtraction problem:
                8x + 2y=30
                7x + 2y=24   
- Subtract the equation just like you would normally. This should leave 1x=6 or x=6.
- Now that you have your x value, plug it in as x for one of the equations. For the 2nd equation, this leaves: 
                42+2y=24 then
                2y=-18 then
                y=-9
- Double check your y value by plugging x=6 into the first equation. This should also leave y=-9.
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Range corresponds to the values of y on the y-axis. If we see the graph the minimum value of the y-coordinate is -2 and then it tends to increase from it. We do not know till where the y values will increase in the figure it shows 6 but it's still actually increasing we keep on tracing the graph but the minimum value will always remain the same which is -2 . So we can say that the range of the function is
 
Where f(x) is the function and since the values of y on the y-axis increase from -2 we can say that the function has the range of values greater than or equal to -2
