Answer:
y = -3m + 7
Step-by-step explanation:
Given the two point:
- A (2, 1)
- B (5, -8)
We use Slope-Intercept Form to create the equation of the line that goes through the two points above
y =mx + b where m is the slope and b is the y-intercept
Step 1: find the slope of it
<=> m =
=> our equation: y = -3x + b (1)
Now, plug one of the points (either one!) together with m into (1), we have:
1 = -3*2+ b
<=> b = 7
Hence, the equation is: y = -3m + 7
Hope it will find you well.
