Answer:
y=-1/4x+8
Step-by-step explanation:
To find the equation of a line that is perpendicular to a line, you would take the opposite reciprocal of the slope.
Before that, we need to change the equation into slope-intercept form.
-4x+y=10
y=4x+10
The opposite reciprocal of the slope is -1/4.
Now, let's use the point-slope formula to find our equation of the line that passes through (-4,9).
y-y1=m(x-x1)
y-9=-1/4(x-(-4))
y-9=-1/4x-1
y=-1/4x+8

we know that

In this problem we have

substitute the given value in the formula and solve for F




 
        
                    
             
        
        
        
If it's written correctly, I believe the points are (5 , 140) and (20 , 520). First equation indicates a parabola and the second a line. The parabola crosses the line at two points.
        
             
        
        
        
10 15 20 since i am pretty sure the rest are a triple(definitely 3 4 5 and 7 24 25 is a triple0
