Answer:
1) y=2x+5
2) y=-2x+3
3) y=4x+2
Step-by-step explanation:
Okay so the y intercept formula is
y=mx+b
Y is a random y coordinate
m is the slope
x is a random x coordinate
b is y intercept
So first we can make the equation equal to y
Find the slope *dont forget the negatives*
When found the slope, plug it in for b and add x next to it
so now your equation would be something like
y=mx
Now for the B we just start from the origin.
And find the first coordinate to pass the y axis
Now just put it in *ex: if 0,3 is the first coordinate, put 3 as B.
now young got it!
