We can set up a proportion here. On map scales, the scale goes like:
“1 (length on the map) : x (real life length)”
Here, we have 2 : 8. We need to make it so the first number is 1, because thats easier for measuring.
2 : 8 /divide both sides by 2
1 : 4
The scale would be 1in : 4mi (in other words, 1 inch on the map corresponds to 4 miles in real life).
The answer is the first one!
(2,-1)(8,4)
slope = (4-(-1) / (8-2) = (4 + 1)/6 = 5/6
y - y1 = m(x - x1)
(8,4)...x1 = 8 and y1 = 4
slope(m) = 5/6
now we sub
y - 4 = 5/6(x - 8) <==point-slope form
y - 4 = 5/6x - 20/3
y = 5/6x - 20/3 + 4
y = 5/6x -20/3 + 12/3
y = 5/6x - 8/3
-5/6x + y = - 8/3...multiply by -6
5x - 6y = 16 <==standard form
