Answer:
Step-by-step explanation:
eq of a line through (x1,y1) and slope m is
y-y1=m(x-x11)
y+3=3(x+4)
y+3=3x+12
y=3x+12-3
y=3x+9
Answer:
<h2>

</h2>
Step-by-step explanation:
To find y when x=4, we must first find the relationship between them
The statement
y varies directly with x is written as
<h3>

</h3>
where k is the constant of proportionality
From the question
when y = 1/5
x = 3
Substitute the values into the above formula and solve
That's
<h3>

</h3>
So the formula for the variation is
<h3>

</h3>
From the question
when x = 4
<h3>

</h3>
Hope this helps you
The answer is 336 because since combinations are a way to calculate the total calculations so the answer is 336.
