Which of the following is the equation of the line graphed below?

D. y=2x+2

Step-by-step explanation:

the equation of a line is given by:

y=mx+b

m is the slope and b is the y-axis interception (0,b)

hence using the graph we can see that b=2, m can be obtain using 2 points one would be (0,2) and the other would be (-1,0)

m=(0-2)/(-1-0)= 2

so we have:

y= 2x+2

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
