Write the equation of the line if the slope = -3/5 and the line passes through (-4, 0). show your work.

3x+5y+12=0

Step-by-step explanation:

This information is given in the question:

m=-3/5

x1=-4

y1=0

The formula for the equation of a line is:

y-y1=m (x-x1)

From this we can make a substitution

y-0=-3/5 (x--4)

Next simplify

y=-3/5 (x+4)

Multiply both sides of the equation by 5

5y=-3x-12

Make the right side of the equation equal to zero

3x+5y+12=0

This is the equation of the line in general form.

Step-by-step explanation:

Given that :

Jack had 4 hours of school.

He spent 45 minutes in the library

1/2 hour on a science lecture  and;

had a lunch break of 25 minutes

The objective is to determine how much time is left for the school to get over and we are to write the answer as a fraction.

In order to do that, we will have to convert the minutes into hours,

we all know that; 60 minutes = 1 hour.

Then,

45 minutes = (45/60)hour = 3/4 hour

25/60 minutes = 1/4 hour

Therefore, the amount of time left  for the school to get over is:

=

=  

=

=
