There's no way for us to use the table if you won't share it with us.
The equation is already is slope intercept form where you can easily point out the gradient, or the slope, and the y intercept.
y=mx+b where m is the gradient, and b is the y intercept.
Since there is no m, the gradient is 1.
The y intercept had x=0 and y=b
b in this case is 6
the y intercept= (0,6)

Divide the shape into 2 rectangles:
Area = Length x width
1 : 7 x 30 = 210
2: (25 -7) x (30-20) = 18 x 10 = 180
Total area = 210 + 180 = 390 square feet.
