Y=2x-1 because (y2-y1)/(x2-x1) is 10/5 which is two. Using point slope form y-y1=m(x-x1) we find y=2x+1.
Answer:
16/1 I think
Step-by-step explanation:
So first we find the change
45 to 15=45-15=30
change is 30
rate of change=(change)/(original)
original=45
change=30
30/45=10/15=2/3=0.66666666=66%
rate of change is 66.66%
Answer:

Step-by-step explanation:
A suitable common denominator is 4k^2. (This eliminates the first and last choices.)

Factor and set each factor equal to zero:
x = -3, 3, 2i, -2i
