A line pass through the point (4,-2) and has a slope of 1/2 what is the value of (-4,a)

a=-6

Step-by-step explanation:

slope=(y2-y1)/x2-x1)

1/2=(a-(-2))/(-4-4)

1/2=(a+2)/-8

a+2=1/2×-8=-4

a=-4-2=-6

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
