Find the equation of the line specified. The slope is -7, and it passes through ( 5, -3).
Montano1993 [528]
The general equation of a line is
y= ax + b
where a is the slope
So a = -7
So y= -7x + b
But it passes through the point (5, -3)
Substitute the coordinates to calculate b:
So -3 = -7(5) + b
-3 = -35 + b
b= 35-3
b= 32
So the equation of the line of slope -7 and passing through the point (5, -3) is
y= -7x + 32

The quantity a varies directly with b and c and inversely with d. The quantity d is tripled. Which of the following must be true
Vinvika [58]
Lets name the quantity Q
Q=k* \frac{b*c}{d} 

When quantity d is tripled, we get





Q=k \frac{b*c}{3d} 

To be the relationship the same, we see that we need to 
multiply  /numerator  / by  /3 


Q =  k \frac{3bc}{3d} 

So the answer should be 
"The product of c and b must be tripled."
