find f(a) if f(t) equals 2t2 t  2 find the slope of a line that passes through (2,4,)(7,8)

f(a)=2a^{2}  a 2
slope= (48)/(2(7)) figure out how I did that. 
for the sloe question the multiple choices are either 4/9,4/5,5/4,9/4 which one is it

the slope question was a line that passes through 2,4 and 7,8

find the slope of a line that passes through 2,4 and 7,8 the mutiple choices are 4/9, 4/9, 5 /4, 9/4 which one is it
