6.3
Step-by-step explanation:
You can find the distance with a distance formula (need the points and it has a big, long square root) BUT, when you have an image like this graph you can totally see a right triangle and use the Pythagorean Theorem (distance formula is derived from Pythagorean theorem anyway) see image
It is 1/6 or .16 I used Photomath
39 x 10
= 390
39 x 40 (390 x 4)
= 1,560
39 x 2
= 78
1,560 - 78
= 1,482
ANSWER: 1,482
