Answer:
B)-4
Step-by-step explanation:
y=mx+c
sub in a point and gradient/slope to get c
-7=3(-1)+c
-7=-3+c
-7+3=c
c=-4
y=3x-4
if u looking for the y intercept make x=0
y=3(0)-4
y=-4

Step-by-step explanation:
Answer:
Step-by-step explanation:
we know that
If two lines are parallel then their slopes are equal
The equation of the given line is
the slope is 
so
the slope of the parallel line to the given line is also
Find the equation of the line that is parallel to the given line and passes through the point (6, 5)
we have
The equation of the line in point slope form is
substitute
Convert to slope intercept form
isolate the variable y
Answer:
Number of weeks in a year = 52 weeks
If in a normal year when each package of flea treatment lasts for 4 weeks, then in a year there Jim's dog will have to be treated for
Where as, when the fleas are bad in a year, the treatment lasts for only 3 weeks.
Then in a year Jim's dog would get
So Jim's dog will get 17- 13 =4 treatments more.
4 treatments that are made in 3 weeks each will be 4×3 =12 weeks more treatment
