Question

Find the equation of the line passing through the points (3,8) & (5 ,-1)​

Answer 1

Answer:

y=-9x/2 + 43/2

Step-by-step explanation:

y=mx+b

m=(y2-y1)/(x2-x1)

m=-9/2

(3,8)

8=-9/2 *3 +b

b= 43/2

(5,-1)

-1=-9/2 * 5 +b

b=43/2

in both cases b value is same

therefore y=-9x/2 + 43/2
