Answer:the value where the line crosses the y axis
Step-by-step explanation:
its crossing through the y-axis not the x-axis because. The y-intercept is where the line crosses the y-axis. for example, you see the line cuts across the y-axis at -2. This makes our y-intercept -2.
Answer:
One difference would be the slope of the lines. One similarity would be where the lines cross the y-axis.
Step-by-step explanation:
This can be seen when we use the equation y=mx+b. m stands for the slope of the line and b stands for where the line is going to cross the y-axis.
I hope this helps.

Answer:

Step-by-step explanation:
So generally an exponential equation is expressed in the form:
and:
. In this case we see that as x increased by 1, the y-decreases, BUT the absolute value is increasing, so it's really just reflected.
Plug in known values:


So if you think about it. you really have
-2 = a * b
-4 = a * b * b
since ab = -2, then we can substitute this into the second equation
-4 = -2 * b
-4 = -2b
Divide both sides by -2
b = 2
You can also deduce that b=2, by realizing to go from -2 to -4, you have to subtract 100% of -2 from -2. This means r=1, so b=1+1, b=2
Anyways, now it's time to solve for a, by plugging in a point as well as b.
-4 = a(2)^2
-4 = 4a
-1 = a
You can verify this by using the other point
-2 = -(2)^1
-2 = -(2)
-2 = -2
So the equation is:
