The formula for point slope form is (y-y1) = m(x - x1)
In this formula m will always be the slope. So, you can substitute 3 in for m
(y-y1) = 3(x-x1)
y1 is the y-coordinate and x1 is the x-coordinate. So, you can substitute them in and you will be done.
(y - 1) = 3(x - (-2))
But since it is minus a negative it changes to a positive so it would be:
(y -1) = 3(x + 2)
Hope this helps!
Answer:
240 girls
Step-by-step explanation:
Let number of girls be x.
160:x = 2:3
Multiply right side by 80--> 160:x = 160:240
x=240.
So there are 240 girls.
The population increases by a factor 1.0167 every year so the require figure is:
103 * 1 . 0167^5 = 112 million
Answer:
You started with 32 muffins
Step-by-step explanation:
Let x represent how many muffins you started with.
Then three-fourth of this muffins equal 24.
This gives us the equation:
Multiply both sides by 4/3 to obtain:
This simplifies to give:
