y = –5x + 19
y = one fifthx + 91over5
y = one fifthx – 19
y = 5x – 19
To find the correct equation, we can plug in the given point (15, -16) into each option and see which one is satisfied.
Let's try:
1. y = -5x + 19
-16 = -5(15) + 19
-16 = -75 + 19
-16 = -56
This equation does not hold.
2. y = 1/5x + 91/5
-16 = 1/5(15) + 91/5
-16 = 3 + 91/5
-16 = 16.2
This equation does not hold.
3. y = 1/5x - 19
-16 = 1/5(15) - 19
-16 = 3 - 19
-16 = -16
This equation holds.
4. y = 5x - 19
-16 = 5(15) - 19
-16 = 75 - 19
-16 = 56
This equation does not hold.
Therefore, the correct equation is y = 1/5x - 19.
