Answer:
y = -x + 10
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope-Intercept Form: y = mx + b
Step 1: Find slope m
m = (11 - 9)/(-1 - 1)
m = 2/-2
m = -1
y = -x + b
Step 2: Find y-intercept b
9 = -(1) + b
9 = -1 + b
b = 10
Step 3: Rewrite linear equation
y = -x + 10
