Sketch the plane curve in the xy-plane and find its length over the given interval:(adsbygoogle = window.adsbygoogle || []).push({});

r(t) = (6t-3)i + (8t+1)j on [0,3]

Here's what I've got so far:

r'(t) = 6i + 8j

llr'(t)ll = sqrt of 6^2+8^2 = 10

s = integral 0-3 10dt

= 10x ]0 to 3

= [30-0]

= 30

I just need help on how to sketch this plane curve. Thanks.
