Pythagoras theorem is c^2 = b^2 + a^2
so when you plug in the numbers its 12^2 + 5^2 =169
which means 144+24=169
square root 169 = 13
AB =13 cm
hope this helps I tried my best. xx
Answer:
y = (-2/3)x-3
Step-by-step explanation:
Hello:
equation is the line is : y = ax+b a is a slope
y = (-2/3)x+b
passing through the point (−3;−1) : -1 =(-2/3)(-3)+b so : b = -3
y = (-2/3)x-3
second solution : you can verify (-3 ; -1) in the equation : y = (-2/3)x-3
