So you’ll have to isolate the y by dividing the other side of the equation by 3
3y=-x-3
y=-1/3x-1
-1 will be your y intercept and the slope will be -1/3
you’ll start your line by plotting (0,-1)
then from that point you’ll count down one, right 3
or up one, left 3
hope this helps (:
4/5 pounds for 3 $
hence for 1$ we get 4/15 pounds
then for 10$ we would get 4*10/15 =40/15 = 8/3
A cosine equation with 5pi/8 involved brought down by 2. That is the best I can help from what I remember from High School.
1/4x + 5 = =4
subtract 5 to both sides
1/4x = 4 - 5
1/4x = -1
multiply 4 to both sides
x = -1 x 4
x = -4
