Carlos is a service technician for office equipment. The cost for a service call from Carlos is represented by the linear equation y = mx + b, where x is the number of hours Carlos spends on a service call and y is the total cost of the call. Which of the following is true?

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
