I think it's true.
Because any number added to 0 is equal to itself.

Answer:
1 and a half miles
Step-by-step explanation:
1/2 hour = 3/4 miles
1 hour = 2(3/4) miles
the slope intercept form is y=mx+b
since the line intersects at (0,3) b= 3
since the slope is 0 m= 0
so the equation would be y=0x+3 or y=3
