Since area is given by a(x)=10x then, a.) x=5cm a(5) = 10(5) a(5) = 50 cm² x=6cm a(6) = 10(6) a(6) = 60 cm² b.) the slope is defined by the equation y = mx + b where m is the slope and b is the y-intercept using the given function, a(x) = 10x, where y in that case is a(x) then we can say that the m=10 therefore, the slope is 10. by inspection, there is no constant term or 'b'. then we can say that b=0 therefore, y-intercept is zero.
