Answer:
y = 3x - 5
Step-by-step explanation:
So first take any two points from the graph.
(0, -5), (2, 1)
The slope is 
y = mx + b
b is the y intercept
The y intercept is (0, -5) as this is where the line intersects the y axis.
y = 3x - 5
0. The two lines are parallel because they have the same slope. You can find this by using the slope formula.
Circumference = 2πr
So the circumference of the track is C = 2π .2 or .4π
3 times around the track is .4π x 3 or 1.2π - this is the answer but most teachers will want you to use 3.14 for pi.
so 1.2 x 3.14 = 3.768 km
Do you notice that I waited until the end to use the actual value of pi (3.14) in my calculations.
Keeping things in pi units until the very end saves time.
Answer:
1. y= |x| -15
2. y = -|x| +3
Step-by-step explanation
.The V shape means absolute value (the | | ), since its upside down, the equation has to be negative. The tip of the V doesn't start at 0 like normal, it's up 3, so the equation has a +3 at the end. The x intercept at (3, 0) is just so you can check your work. If we plug in 3 for x, we do in fact get 0 for y.
Not sure, if correct but here.
