It would go by (-4,2) then (0,-2) next would be (2,4)
Y = x - 1
because the gradient is 1 and the y-intercept is -1
The formula A=1/2bh is used to find the area of a triangle. You can find from the diagram that the base of this triangle is 9cm, and the height is 4cm. Plug those numbers into the area of a triangle formula.
A=1/2(9)(4)
Multiply to get 18 square cm, which is choice D.
