In order to be parallel to a line, two lines must have the same slope. The slope of y=3x+2 is 3. So the slope of the other equation has the be 3. y=3x+b. Now we can plug in the x and y values given by the point to calculate the b in the equation.
-3=3(-1)+b
-3=-3+b
b=0
So the equation is y=3x
20x-80=-20
-80 -80
20x= -100
/20 /20
x=-5

Answer:
5
Step-by-step explanation:
For an exponential function of the form ...
f(x) = a·b^x
the "multiplicative rate of change" or "growth factor" is the base of the exponential term: b.
Comparing this form to your function, we see that ...
f(x) = 2·5^x
a = 2, b = 5
The multiplicative rate of change is 5.
