For the first question you need to find the formula for the rectangle, after you did that fill it in. and find your answer.
The functional equation of the line is f (x)=a*x+b
you have already a: -4 -->f (x)=-4 x+b
Now you can use the point (3;-3)
3 is the x-coordinate and -3 the f (x)-coordinate
--> -3 = -4*(3) + b Now you can solve it
-3 = -12+b (+12)
b = 9
ANSWER: f (x) = -4x + 9
Assuming the +'s are actually x's 1/2 of 3 is 1.5 and 1.5 divided by 7 is 1.5/7.(answer is 1.5/7) hopefully I'm right.
