ANSWER:
The phrase is a times the x is added to b .
SOLUTION:
Given that, we have to write an expression with two terms.
One term should have a coefficient with a variable and the other term should be a constant.
Let the expression be coefficient x variable + constant
Name the coefficient, the variable, and the constant in the expression.
Let us name coefficient with a, variable with x and constant with b
Then we have to write a word phrase for your expression
Now, the expression is ax + b
Expression in word phrase is a times the x is added to b.
Hence, the phrase is a times the x is added to b
