Try answer C or B because either one could be the right answer
Perpendicular is slope multiplies to -1
for
ax+by=c
slope=-a/b
4x-3y=6
-a/b=-4/-3=4/3
perpendicular to 4/3 is -3/4
point slope form
y-y1=m(x-x1)
for slope=m
a point is (x1,y1)
point (4,-2)
slope is -3/4
y-(-2)=-3/4(x-4)
y+2=-3/4(x-4)
or converted
y=-3/4x+1
or
3x+4y=4

Now it is up to you to figure who was at the greater depth. I did the calculations for you all you have to do is compare:)))) GOOD LUCK its not hard now
The plan for a gym membership will be a linear equation, in the form y=mx+b, where b is the base fee, m is the cost per month, and y is the total cost. As long as the graph of this line for both gyms intersect, this point of intersection is where the cost for both gyms intersect. If you have two parallel lines, however, there will be no point of intersection.
For example, Gym A charges a $20 base fee plus $20 for each month. Gym B charges a $25 base fee plus $20 for each month. These are parallel and will never intersect.
To complete the problem (5.2 - 4.5) - 5.5(4.8) you have to start with solving the numbers inside of the ( )'s.
Once you do this you should get .7 - 5.5(4.8).
Then you need to multiply to get .7 - 26.4.
Now all you have to do is simplify, -25.7
There you go! If you have any more questions about this or anything else just let me know! ;)
