Answer:
y = -4/5x - 0.8
Step-by-step explanation:
A(-6, 4)
B(4, -4)
Find slope using the two points above:
m = (y₂ - y₁) / (x₂ - x₁)
= (-4 - 4) / (4 - (-6))
= -8 / 10
m = -4/5
Find y-intercept using m from above and anyone point, let's use (-6, 4):
y = mx + b
4 = -4/5(-6) + b
4 = 24/5 + b
b = -0.8
Use m and b from above to form equation of line:
y = mx + b
y = -4/5x - 0.8
128 is your answer!!:)
1 meter=100 cm
So 100+28=128! That's your answer!!:)
