The last one. Mark a point at 10 on the y-axis, go up 5 and right one and mark this point.
An expression is just a mathematical phrase. A numericalexpression contains numbers and operations. An algebraic expression is almost exactly the same except it also contains variables!
Hope this helped :)
Answer:
Distance = 5
Step-by-step explanation:
D= sqrt (x1-x2)^2 + (y1-y2)^2
(5-2)^2 + (8-4)^2=3^2 + 4 ^2 = 9 +16 = 25
Sqrt of 25 = 5
Distance = 5
