Answer:
The correct answer would be A) (4, 49.6)
Step-by-step explanation:
In order to find the equation, we first have to start with the base form of direct variation.
y = kx
Now we input the k value.
y = 12.4x
Now that we have this, we can try the ordered pairs and look for which satisfies the equation.
y = 12.4x
49.4 = 12.4(4)
49.4 = 49.4
Since this is the true statement, this is the ordered pair that works.
Perpendicular to the line y = 5x - 9
m= -1/5
the line passing through the point (1, 4):
4=-1/5*1+q
q= 21/5
the equation is:
y= -1/5x +21/5
or
x+5y-21=0
