Question

plz can i just have answers must hurry and get this done

Answer 1

plz

Answer 2

@borak help me plz

Answer 3

the function called rate change of function is
2x-5y = -15 ; 2x+15 =5y ; 2/5x +3 = y this postive rate of change not !! negative

Answer 4

y= -4x+9 // this negative rate of change

Answer 5

the slope = rate of change // slope give you inforamtion about the nature of the function

Answer 6

part 3 : - you see that x is going up the value is decreasing more then the slope is negative

Answer 7

back my pc shut down

Answer 13

yes

Answer 14

rate of change is the slope

In y = mx + b form, the slope is in the m position

1.) 2x - 5y = -15
-5y = -2x - 15
y = 2/5x + 3
slope is 2/5.....so its positive (A)

2.) y = -4x + 9
slope is -4 .... so its negative (B)

slope formula : slope = (y2 - y1) / (x2 - x1)

3.) (2,-10)(4,-16)
slope = (-16 - (-10) / (4 - 2)
slope = (-16 + 10) / 2
slope = -6/2
slope = -3....so negative (B)

4.) (-3,15)(-2,11)
slope = (11 - 15) / (-2 - (-3))
slope = -4 / (-2 + 3)
slope = -4 / 1 .... so its negative (B)

yep...its A,B,B,B
