Can someone help me and do a step by step answer? I’d appreciate it a lot and I’ll give you brainlist

y =  1/2x + 4 1/2

Step-by-step explanation:

(9 , 9) (3 , 6)

slope (m) = Rise (Δy) /run (Δx) = (9-6) / (9-3) = 3/6 = 1/2

(y-6)/(x-3) = 1/2

y-6 = 1/2 (x-3) = 1/2x - 3/2

y = 1/2x + 9/2 = 1/2x + 4 1/2

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
