Question

Indicate in standard form the equation of the line passing through the given point and having the given slope.

D(5, -2) m = 2/5

Answer 1

y=mx+n
m=0.4m x=5, y=-2

-2=0.4*5+n
-2=2+n
n=-4

So:

y=0.4x-4

Answer 2

x = 5 , y = -3 m = 2/5

y = mx + b
-2 = 2/5 * (5) + z
-2 = 2 + n
n = -4 !

Answer 3

you
