equation for a linear function (14,0) perpendicular to the given of g(x) = 2x + 5

Question

Need help making the equation 

Answer 1

if it is perpendicular, its slope would have to be -1/2 to get the equation, substitute the given point and the slope into the slope intercept equation, y=mx+b 0=-1/2(14)+b 0=-7+b b=7 y=-1/2x+7
