Question

I need help with these Please

Answer 1

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!
