I don't know either. sorry.
Answer:
y = -3x - 1
Step-by-step explanation:
y = mx + c
m = (-4-2)/(1-(-1)) = -6/2 = -3
y = -3x + c
When x = -1, y = 2
2 = -3(-1) + c
c = 2 - 3 = -1
y = -3x - 1
first, spread the parenthesis. y+2=1/2x-1.5
second, add 1.5 to both sides. y+3.5=1/2x
third, multiply by 2. 2y+7=x
if you are solving for y, do not do the third step, instead, subtract by 3.5. y=x-3.5
hope this helps!
ANSWER: x=2y+7 or y=x-3.5
Answer:
If it took the motorcycle 2 hours to cover 20km, then the average speed is 10km per hour.
Speed is equal to distance over time. So 20km divided by 2 hours is 10 km per hour.
