Let's find slope using


y_(2) - y_(1) / x_(2) - x_(1)

-2 - 3 / 8 - 5 = -5/3

So m, or slope, equals 5.

Now, let's solve for b.

-2 = -5/3(8) + b
-2 = -40/3 + b
Add 40/3 to both sides.
11 1/3, or 34/3 = b

So your equation would look like

y = -5/3x + 34/3

(5,3)(8,-2)
slope = (-2 - 3) / (8 - 5) = -5/3

y = mx + b
slope(m) = -5/3
use either of ur points...(5,3)...x = 5 and y = 3
now we sub and find b, the y int
3 = -5/3(5) + b
3 = -25/3 + b
3 + 25/3 = b
9/3 + 25/3 = b
34/3 = b

so ur equation is : y = -5/3x + 34/3....but we need it in standard form

y = -5/3x + 34/3
5/3x + y = 34/3....multiply both sides by 3
5x + 3y = 34 <==
