C.x=-7.7 and x=-1.3 should be the answer
I don't think when this number is added to any other rational number would produce an irrational number
But we do know that when 0.4 is added to an irrational number it would be irrational.
e.g; 0.4 + pi is irrational, etc, etc
So any other irrational number would make it irrational
Answer:
y= 2/3 x
Step-by-step explanation:
First plot the points on a Cartesian plan
You will notice a straight line passing through the origin (0,0)
Find the gradient of the line;
m=change in y/change in x
m=2-0/3-0 =2/3
Find the equation of the line
y-2/x-3 =2/3
3(y-2) = 2(x-3)
3y-6= 2x-6
3y=2x-6+6
3y=2x
y=2/3 x + 0
By creating a common denominator for all of the fraction (12) the answer would be 7 3/12 or 7 1/4
