HELP ME

Step-by-step explanation:

grab two points from the line then subtract x with x and y with y and you will get a fraction which will be mx and -7 will be your b

y=(the answer you got)*mx*-7

this is how you sub then

1-1

2-3  and it will look like a fraction

i explained it better for you but you have to do the work so you can better understand it

(you can always find b by looking for the point on the y-axis the line crosses)

2nd one in the first row is correct
