Y=12+2x
y represents the number of pieces she now knows, x represents the number of weeks she has taken lessons, 2 is the slope (the number of pieces she'll learn each week), and 12 is the y intercept (the number of pieces she knew before taking lessons).
To solve the equation for 11 weeks, we replace x with 11.
2×11+12= 24
y=24
