Answer:
y = (-2/5)x - 8/5
Step-by-step explanation:
Start with the slope-intercept form y = mx + b.
Replace m with -2/5, y with 2 and x with -9:
2 = (-2/5)(-9) + b
Simplifying this, we get:
2 = 18/5 + b, or 10/5 = 18/5 + b
Subtracting 18/5 from both sides yields b = -8/5, and so
the desired equation is
y = (-2/5)x - 8/5
