We know that
1 hour----------> 60 min
step 1
convert hours to minutes
<span>4:15---------> 4 hour +15 minutes------> 4*60+15-----> 255 minutes
step 2
</span><span>subtract 45 minutes
</span>255-45--------> 210 minutes
step 3
convert to hour
1 hour----------> 60 min
x-----------------> 210 min
X=210/60---------> X=3.5 hour
3.5 hour
that means
3 hour+0.5 hour
and 0.5 hour is-----------> 0.5*60----> 30 minutes
therefore
3.5 hour-------> 3 hour +30 minutes-------->3:30 pm
the answer is
3:30 pm
Answer:

Step-by-step explanation:
1) the equation of the given line in the slope-interception form is:
y= 3/5 x -2;
the equation of the required line is
y=slope*x+i;
2) if the required line is parallel to the given one, it means, the value of its slope is the same, it means 3/5;
then the equation of the required line is
y=3/5*x+i;
3) if the point (-4;-1) belongs to the required line, then it is possible to substitute its coordinates into the equiation of the required line
-1= 3/5*(-4)+i;
4) it is possible to calculate the value of 'i':
i=7/5;
5) if slope=3/5, i=7/5, then the required equation of the line in slope-interception form is:
