Plz help me. If you cant give me answer than at least plz explain to me how to do this so i can get a better understanding of this...thx

Um i know a good sight that will do this for you it picture homework

Step-by-step explanation:

y = mx + b    

Step-by-step explanation:

Substitute in the slope intercept formula

m = slope  

x = first number in the point

y = second number in the point  

and solve for b

Question 1

m=-1/2, x= -4  y=-2  substitute

-4 = -1/2(-4) + b

-4 = 2 + b

-4 -2 = 2 -2 + b

-6 = b

y=-1/2x -6

4th option is correct xy=-10

if this was to u plzz mark me the brainliest
