First you need to figure out the slope:
y2-y1/x2-x1=(1+5)/(-5-7)=-1/2
y+5=-1/2(x-7)
y=-1/2x-3/2
Answer:
A tuple cannot be changed once it is created.
Step-by-step explanation:
A is the answer because it costs $295 for the ticket and $271.9 in total if he drives in car. So therefore driving is less expensive.
Answer:
y=-x^2
Step-by-step explanation:
given that y = x^2 is the function.
For equivalent to -y, we can multiply this equation both the sides by -1
We get -y = -x^2
Hence option G is right.
Also y =x^2 is a parabola with vertex at origin open up.
Hence if F is selected we get -y =(-x)^2 = x^2, this will make the parabola open down and hence this option is wrong.
H: -y=-x is wrong because this represents a line but we had original equation as that of a parabola
J) -y = x^(-2) means x^2y =-1
This implies that rate of change of y = 2/x^3 but rate of change of y has to equal 2x since y = x^2 is original. Hence only option G is right.
