----------------------------------------------------------- Make y the subject : ----------------------------------------------------------- y - 3 = 4(x + 8) y - 3 = 4x + 32 // Apply distributive property y = 4x + 35 // Add 3 to both sides
----------------------------------------------------------- Find a point on the line : ----------------------------------------------------------- When x = 0, y = 4(0) + 35 // Sub x = 0 into the equation y = 35 // Combine like terms Point = (0, 35)
----------------------------------------------------------- Answers : (a) Slope = 4 (b) One point on the line is (0, 35) -----------------------------------------------------------
So what I did was divide $50(Amount at the end) by 6 (the number of months). Which would give me the amount of money he made per month ($8.333...). So then $8.333.../$5000(Total $) is .166...% (Interest rate)
