I hope this helps, wrote out the explanation cause its better on paper.
This is a linear function in the slope - intercept form:
y = m x + b and we need a standard form:
a x + b y = c
y = 1/8 x + 7 / * 8 ( we will multiply both sides of equation by 8 )
8 y = x + 56
- x + 8 y = 56 / * ( - 1 )
x - 8 y = - 56

Answer: The correct option is third. The area of the figure is 25 cm square.
Explanation:
It is given that Each small square on the grid is 1 cm².
In the given figure there are 2 congruent parallelograms and 4 congruent triangles. As shown in figure below.
From the figure it is noticed that the length and breadth of the parallelogram is 4 and 3 respectively.
Area of the parallelogram,
Area of a parallelogram is 12 cm². So, the area of 2 parallelogram is
The height of the triangle is 0.25 and the base of the each triangle is 2.
Area of a triangle is,
Area of one triangle is 0.25 cm², so the area of 4 triangles are 1 cm².
Total Area of the figure is,
Therefore, the total area is 25 cm².
I think that it would be C, but I am debating on C and D. I'm pretty confident that it's C, though. Pretty sure.
