Answer:
a=-2, b=1.
Step-by-step explanation:
1) according to the condition it is required to find the equation of line, which passes through points A(-3;7) and B(4;-7);
2) the equation of this line can be made up using the formula:
![\frac{x-X_A}{X_B-X_A} =\frac{y-Y_A}{Y_B-Y_A};](https://tex.z-dn.net/?f=%5Cfrac%7Bx-X_A%7D%7BX_B-X_A%7D%20%3D%5Cfrac%7By-Y_A%7D%7BY_B-Y_A%7D%3B)
![\frac{x+3}{4+3} =\frac{y-7}{-7-7} ; \ < = > \ x+3=\frac{y-7}{-2}.](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B3%7D%7B4%2B3%7D%20%3D%5Cfrac%7By-7%7D%7B-7-7%7D%20%3B%20%5C%20%3C%20%3D%20%3E%20%5C%20x%2B3%3D%5Cfrac%7By-7%7D%7B-2%7D.)
3) if to re-write the last equation, then
y=-2x+1;
4) finally, a= -2; b=1.
Answer:
well you cant buy it in 3 months because that would equal 1,200$
so you would need 300$ more to buy the sound system
