Answer:
Step-by-step explanation:
slope = (y2 - y1) / (x2 - x1) Pick (5,-9) and (11,-10.2) as your 2 points. This is a random choice. Any two points could be chosen in any order.
y2 = - 9
y1 = - 10.2
x2 = 5
x1 = 11
m = (-9 - -10.2) / (5 - 11)
m = 1.2 / -6
m = - 0.2
Use the first point to find the y intercept (b)
x = 5
y = -9
General equation (y = mx + b)
-9 = -0.2*5 + b
- 9 = -1 + b Add 1 to both sides.
-9+1 = b
b = - 8
Answer: y = -0.2x - 8
