In slope intercept form it would be y=2x+8
Answer:
Rational
Step-by-step explanation:
√4 asks "what times itself is 4?"
The answer is 2.
2x2=4
√4 = 2
2 is rational.
Answer: Keisha can run faster than Stephan.
Step-by-step explanation:
Let's figure out how long it takes for them to run a mile.

It would take Stephan 5.25 minutes to run a mile

It would take Keisha 4.52 minutes to run a mile
Since Keisha takes less time to run a mile she is faster.
Answer:
y = x - 40
Step-by-step explanation:
Points on the graph: (0, -40) and (60,20)
Slope:
m=(y2-y1)/(x2-x1)
m=(20+40)/(60-0)
m=60/60
m = 1
Slope-Intercept
y - y1 = m(x - x1)
y + 40 = 1(x -0)
y + 40 = x
y = x - 40
