Ken’s predicted temperature for april is 7ºc. his prediction for may is 2ºc higher than april. he used the number line to solve the problem, starting at 0, moving right to 7, and then moving 2 units to the left. explain ken’s error what did he do

He should move 2 units further to the right of 7

Step-by-step explanation:

April's temperature = 7°C

Prediction for May is 2ºC higher than April.

So, May's temperatue =  7°C+2ºC =9ºC

Ken's used the number line to solve the problem.

Step 1)Starting at 0, moving right to 7

Step 2)moving 2 units to the left.

He did error in step 2 because the temperature is positive and numbers on right of the - are positive

So, he should move 2 units further to the right of 7

So, He did error in step 2 .

Correct steps :

Step 1)Starting at 0, moving right to 7

Step 2)moving further 2 units to the right.
