(0, 207)
We calculate y-intercept by substituting 0 for x.
The equation becomes:
3*62-6*(0)+21=207
y intercept is (0, 207)
B
7 less than 3 times a number (X) is (3x-7), and then the sum of these two numbers means we have (3x-7)+X, and then we know this equals 109, leaving us with:
(3x-7)+x = 109
7cm=7×3ft=21ft
4cm=4×3ft=12ft
here
length=21ft
breadth=12ft
now
area= l×b
=21ft×12ft
=252ft^2
