Answer:
Y = 0.5x-1 is the formula
The equivalent expression on expanding -1/4 (-8x + 12y) is 2x - 3y
<h3>Expansion of expression</h3>
Expansion of expression can be carried out using the distributive rule a shown:
A(B + C) = AB + AC
Note that <u>A is distributed over B and C</u>
Given the expression
-1/4 (-8x + 12y)
-1/4(-8x) - 1/4(12y)
2x - 3y
Hence the equivalent expression on expanding -1/4 (-8x + 12y) is 2x - 3y
