Question

Find the value of y for a given value of x,if y varies directly with x. If y= -166 when x=58, what is y when x= 24.

Answer 1

equation for direct variation \[\huge\rm y=kx\] where k is `constant of variation`
substitute x and y value for their values `y=-166 ,x= 58` solve for k

Answer 2

and then plugin k value into the equation to find y
when x =24
