Answer:

Step-by-step explanation:
using the y=mx+b equation, where m=slope and b=y-intercept, we can place our known slope and y-intercept to form our answer,
:-) hope this helped!
Answer:
v = ± 
Step-by-step explanation:
Given
E =
( multiply both sides by 2 to clear the fraction )
2E = mv² ( divide both sides by m )
= v² ( take the square root of both sides )
v = ± 
Answer:
y + 1 = 3x
Step-by-step explanation:
In order for there to be an infinite number of solutions, the two lines need to be the same.
y+1 = 3x
y=3x-1 are both the same
