The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1.what values should she substitute into the formula?

Step-by-step explanation:

Note that the distance, along a straight line, from A:  -2 to B:  7 is 9 units.

This is found by subtracting -2 from 7, so x2 = 7 and x1 = -2.

Then x = (x2 – x1) + x1 becomes x = (7 - [-2] ) + [-2], or x = 7.  This does not make sense.  

If we ignore this x = (x2 – x1) + x1, and focus instead on finding the division point in this line segment:

4 + 3 = 7, so the longer part of this 9-unit distance will be (4/7)(9), or 36/7 units long, or 5  1/7 units long.  The shorter part will be (3/7)(9), or 27/7 units long.

To check:  determine whether the ratio 36/7 to 27/7 comes out to 4:3, as it must:

36      4*9

= = 4/3.  YES

27       3*9

whats the

they can both be solutions depends on the equation

what is the equation? ?
