Answer:
Van 8 and bus 27
Step-by-step explanation:
v+7b=197
12v+b=123 b=123-12v
v+7(123-12v)=197
v+861-84v=197
664=83v
v=8
8+7b=197
7b=181
b=27
Hello : let A(1;5) and B(-2;14)
the equation is y = ax+b .... a is a slope
a = (yb -ya)/(xb -xa)
a = (14-5)/(-2-1)
a = -3
y = -3x+b
A passes <span>through</span> the line : 5 =-3(1)+b ..... b = 8
y = -3x+8
