Answer:
-5 is the slope and -6 is the y intercept
Step-by-step explanation:
This is in the form
y =mx+b where m is the slope and b is the y intercept
y = -5x -6
-5 is the slope and -6 is the y intercept
x-intercept = (15, 0) y-intercept = (0, 3)
slope (m) = (y₂ - y₁)/(x₂ - x₁) = (0 - 3)/(15 - 0) = -3/15 = -1/5
Point-Slope formula: y - y₁ = m(x - x₁) ; where (x₁, y₁) is one of the given points
y - 0 = (-1/5)(x - 15)
-5y = x - 15
x + 5y = 15
Answer: x + 5y = 15
