Line AB = point A (-4,-7) -> point B (12,4)
Line AB length = (12- -4, 4 - -7) = (16,11)
The point 7/10 of the way is 7/10 of the x coordinates length and 7/10 of the y coordinate length, because that’s what makes up the line.
7/10 * 16 =1.6 * 7 = 11.2
7/10 * 11 = 1.1 * 7 = 7.7
We add these to our start points to get to our point 7/10 along the line
11.2 + -4 = 7.2
7.7 + -7 = 0.7
Answer = (7.2, 0.7)
