Sales at a computer retail store were $1,000,000 in 1982 and $1,790,000 in 1987

let x=0 represent 1982

find the equation giving year sales. estimate sales in 1990.


Could you guys help me with this.

    sales=slope*time+constant

    slope= 1.790/5

    sales= 1.790/5 * (year-1982)+1,000,000

    year is in the format of like 1990

    sales in 1990=1.790/6(1990-1982)+1000000
