Which graph represents exponential decay? On a coordinate plane, a straight line has a negative slope. On a coordinate plane, a curve approaches y = 0 in quadrant 2 and curves up in quadrant 1. On a coordinate plane, a straight line has a positive slope. On a coordinate plane, a curve approaches y = 0 in quadrant 1 and curves up in quadrant 2.

i just took the test, the correct answer is .. 31.5 in.

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
