Question

find an equation of the line having the given slope and containing the given point
m=4/5, (4,-2) y=

Answer 1

m=4/5, (4,-2) y = mx +c [substitute known values into general equation]
-2 = 4/5(4) + c
-2 = 16/5 + c
Subtract 16/5 from both sides to reveal c
-36/5 = c

Now you can write the equation of the given line

y = 4x/5-36/5
