First find the slope of this new line; it's the same as the slope of the "given line," which you unfortunately have not yet given. Let's call that slope "m."
Then, the equation in point-slope form of the new line is
y - (-1) = m(x - [-1]), or y+1 = m(x+1)
Please go back to the original question, obtain the slope of the "given line," and substitute that value for m in y+1 = m(x+1).
First flip the 2nd number. (denominator becomes numerator and vice versa) then multiply the numerators and multiply the denominators. that's the answer.

Step-by-step explanation:
![\frac{42}{\frac{7}{9}} = 42 \times \frac{9}{7} = \frac{378}{7} = 54](https://tex.z-dn.net/?f=%5Cfrac%7B42%7D%7B%5Cfrac%7B7%7D%7B9%7D%7D%20%3D%2042%20%5Ctimes%20%5Cfrac%7B9%7D%7B7%7D%20%3D%20%5Cfrac%7B378%7D%7B7%7D%20%3D%2054)
Dividing by a fraction is the exact same as multiplying by its multiplicative inverse.

Answer:
See below
Step-by-step explanation:
Assuming a number line:
rs + st = rt
3x-16 + 4x-8 = 60
7x -24 = 60
7x = 84
x = 12
