19. Kim owes her friend $245 and plans to pay $35 per week. Write an equation of the
function that shows the amount Kim owes after x weeks. Then find and interpret
the intercepts of the function.
20. Explain the Error Arlo incorrectly found the x-intercept of 9x + 12y = 144.
His work is shown.
9x + 12y = 144
9(0) + 12y = 144
12y = 144
y = 12 The x-intercept is 12.
Explain Arlo's error.
