What is an equation of the line that passes through (0, 8) and (4, 0)?

y = 2 x + 8
y = 2 x + 4
y = -2 x + 4
y = -2 x + 8

Step-by-step explanation:

Say y=ax+b. It goes through (0,8) and (4,0). Therefor we can say 8=a(0)+b which gives us b=8. Then we fill in (4,0) which results in 0=a(4)+8. Given that, a=-2. so y=-2+8

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
