Hello :) how to do this question?:)

a= 2.5, b= 5

Step-by-step explanation:

Since the graph is obtained by plotting y against xy, Y= y and X= xy. (Linear law: Y=mX +c)

Given that the line intersects the vertical axis at (0, ½), the y-intercept is ½.

Equation of the line: Y= mX +½

Given that the gradient is ⅕, m= ⅕.

Y= ⅕X +½

Substitute Y= y and X=xy:

y= ⅕xy +½

Rewrite the equation such that it is in the form of :

Factorise y out on the left hand side:

Make y the subject of formula:

Do not expand at this step as the coefficient of x in the equation is 1. Instead, divide both the numerator and denominator by 2.

Thus, a= 2.5 and b= 5.

the real question is why is this guys last name heavyfoot
