Answer for me please been stuck on it for a while

A

Step-by-step explanation:

Calculate the slope m using the slope formula

m =

with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (1, 9) ← 2 ordered pairs

m = = 3

Note (0, 6) is the point where the line crosses the y- axis, thus

y- intercept = 6

slope of line is 3 and y- intercept is 6 → A

(23*2)-12=x     x=34

step-by-step explanation:

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
