M= 1/2 and point : (4,-3) <br><br> Please help I will give you brainless
Vlad1618 [11]

Answer:

y=1/2x-5

Step-by-step explanation:

We have slope so we just need to find the y intercept.

slope intercept formula is

y=mx+b

(m) is slope

(b) is y int

y=1/2x+b

now apply our given x and y values (4 & -3)

-3=1/2(4)+b

simplify

-3=2+b

subtract 2 from each side

-5=b

put that into our equation

y=1/2x-5
