Answer:
Explanation:
Given that:
Ken's prediction temperature for April 7C.
His prediction for May is 2C higher than April.
He attempts to use the number line to solve the problem.
On a number line, we have the origin at a given point zero, the positive x-axis to the right side, and the negative x-axis to the left side.
So, if Ken's starts from zero and move right to seven and the move units to the left, the error he made was moving 2 units to the left because he supposed to have continued in the right direction by moving 2 units forward. This is because moving to the left side will showing a decrease in the temperature by -2° C and he intends to have 2° C.
