Answer:
y = (-1)*2^(x + 1)
Step-by-step explanation:
This one is not a line. It is something raised to a power. In addition, there is an ugly minus sign somewhere.
First of all, every answer is some sort of power of 2. All of them are 2^x but we don't exactly know how x words. It is not a simple y = 2^x because the first one is - 4 not - 2.
So there is an extra power somehow.
Try
y = 2^(x + 1) That looks promising
x = 1
y = 2^(1 + 1)
y = 2^2
y = 4
===============
Try another one
x = 2
y = 2^(2 + 1)
y = 2^3
y = 8
==============
I think you'll find that the other two are well behaved. and come to the answer (except for the minus) as they should.
What about that minus.
y = (-1)*2^(x + 1) should give a minus y value for any term.
Step-by-step explanation:
z = (x − μ) / σ
z = (65 − 69) / 3.5
z = -1.14
If the equation is in standard form:ax+by=c then you just set x equal to 0 to find the y intercept and set y equal to 0 to find the x intercept. It makes sense, right. The y intercept is when the line crosses the y axis, so x will always be 0, so that is why we set x equal to 0.Step-by-step explanation:
