    Kayla has $1500 in her bank account. She spends $150 each week. Write an equation in slope-intercept form that represents the relationship between the amount in Kayla's bank account, A, and the number of weeks she has been spending, w

    • Slope intercept form is written as A = mw + b
    • m = -150, since spending is a decrease
    • b = 1500, since this is what Kayla starts with when w = 0
    A = -150w + 1500
