Please help! I will mark as brainliest IF answer is right. <3

The equation for a line is y = mx + b

We can find the slope of the given line to be 3/9 which we can simplify to 1/3

Plug this into the equation for a line
y = 1/3x +b

Now we plug (1,1) in for x and y
1 = 1/3 (1) +b

Solve for b by first subtracting 1/3 from each side
1 - 1/3 = b
2/3 = b

Now we take the equation of a line and plug the slope and b back into the equation to get the answer.
y = 1/3x + 2/3

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
