So just try it for x=1 how many will get for y
y+3=2(x-1) for x = 1 will get y+3 =2(1-1) so y+3=2*0 so y+3=0 so y=-3
x=1
y=-3 so choice A.(1,-3) is right sure
hope this will help you
In elementary algebra, a trinomial is a polynomial consisting of three terms or monomials.
So, 4 x 3 is 12, so 4 blades cost 79.74 x 3 (because every turbine has 3 blades each) is 318.96
