Answer:
5
Step-by-step explanation:
You subtract all those distances from 22 to calculate the remaining distance.
22-4= 17
17-5
=12
12-0=12
12-6
=5
So the answer is 5
(Yes I did these in my head)
Let's start by tidying up that equation and put it into slope-intercept form (y = mx + b); from there, we can plug in coordinates.
Let's use the distributive property on the right side:
Now add 4 to both sides
Which simplifies to:
Since that's the equation of our line, now we can plug in coordinates and see what it churns out.
We know that the x-coordinate of P = 4 so let's substitute 4 in for x and calculate the y-coordinate:
So the y-coordinate for point P = 10
