First way: 1 doubled is 1+1, which is 2. 2 increased by 10 equals 12.
Second way: 1 doubled is 1*2, which equals 2. 2 increased by 10 equals 12.
The answers A and C contain correct information but both of them provide different advice. so the answer is literally your opinion between a and c

now, we know the tangent line at (2,4) is y = 8x - 12, now, that's already in slope-intercept form, so, the slope of that tangent at (2,4) is "8" then.
now, that means when x = 2, the slope is 8, so let's use that.
You need to know what the distance jesse traveled is and then the number of gallons of gas she has then you plug it it.
distance equals 15 times the amount of gas in gallons
d=15g
You use Pythagorean theorem to solve it and you get 18.3. Just look at the picture to see how i solved it
