5 - 17
x is adding multiples of 3 to get y
example: 2+3=5, 3+6=9 4+9=13, 5+12=17 and so on.
Ur equation is in this form : y - y1 = m(x - x1)....in this form , point slope form, the slope can be found in the m position.
y - 2 = 3(x - 1)
y - y1 = m(x - x1)
so u see, the slope (the number in the m position) = 3
You can do this: since 1/4 is .25 then just multiply 8 x .25
A+b = c+d
a+b = 770/2 ( a+b+c+d = 770)
a+b = 385
c+d = 385
a+b+a-b = 385+49
2a = 434
a = 434/2
a = 217
a-b=49
217-49= b
b = 168
c+d+c-d = 385+211
2c = 596
c = 596/2
c = 298
c-d = 211
c-211= d
298-211 = d
d = 87
Therefore, a=217, b=168, c=298, d=87
