Step-by-step explanation:
gradient/slope = 3
y-intercept
2x - 3y = 4
3y = 2x - 4
y = 2/3x - 4/3
so y-intercept is double -4/3 so... -4/3x2 = -8/3
the equation of the line is
y = 3x - 8/3 or 9x - 3y = 8
61,62,63 because 61 and 63 came before and after 62
19=1-5h-4h
19-1=-5h-4h
18=-9h
18/-9=h
h=-0.5
Answer: A
Step-by-step explanation: since X>y and y>z
It increases by x2
Sixth number would be 48x2=96
Seventh is 96x2=192
eighth is 192x2=384
Its geometric sequence.
