So 3 times 8 is 24 times x squared. 24x squared, f prime of 1 half is equal to 24 times 1 half squared, which is equal to 24 times 1 fourth, which is equal to 6. So the slope of this line is equal to 6. I'll use m for slope. That's the convention that we use when we first learn it in algebra. So the slope is going to be 6. So the general equation for this line is y is equal to mx plus b.
