What's the rule for translating a point 4 units left and 8 units up?

The second notation is a mapping rule of the form (x,y) → (x−7,y+5). This notation tells you that the x and y coordinates are translated to x−7 and y+5. The mapping rule notation is the most common. Sarah describes a translation as point P moving from P(−2,2) to P (1,−1). Hope that helps you

Iam not good at math i wish i could
