25% is equivalent to 1/4.
(-1, 3)
this is because in a coordinate plane, using the coordinates you gave it is the missing vertice is (-1,3)
Answer:

Step-by-step explanation:
÷ 4 =
x
= 
When you have a fraction divide a number, you need to multiple it's reciprocal
(2x-y = -3 × y = 0 × (0, 0) × ( -1, 1) × (1, -1) =
(2x - y = -3 × y =0 × (0)) ×, × 0 ×, × 1 ×, × -1
if the given point satisfies this equation then it would be its solution
(-1)=2(5)-11
-1=10-1
-1=-1
lHS=RHS
Hence (/,-1) is the solution of y=2x-11
