Answer:
The slope of the line is -3
Step-by-step explanation:
Slope formula:
m = y₂ - y₁ / x₂ - x₁
Get any two points:
(-2, 4) and (-1, 1)
Solve:
m = 1 - 4 / -1 - (-2)
m = -3 / -1 + 2
m = -3 / 1
m = -3
Check for the third point just in case.
Two points:
(-1, 1) and (1 , -5)
Solve:
-3 = -5 - 1 / 1 - (-1)
-3 = -6 / 1 + 1
-3 = -6 / 2
-3 = -3
So -3 is the legit slope of the three collinear points.
When system of equations solved graphically, the solutions are points of interceptions, So here, the solution is the point of interception (0,-5).
Answer (0,-5).
