Explanation:
"the initial statement is "ypropx
"to convert to an equation multiply by k the constant"
"of variation"
rArry=kx
"to find k use the given condition"
y=0.8" when "x=0.5
y=kxrArrk=y/x=0.8/0.5=1.6
" equation is " color(red)(bar(ul(|color(white)(2/2)color(black)(y=1.6x)color(white)(2/2)|)))
