I would make the equation have both of your variables on the same side:
0.1x+y=1
Then I would use the cover-up method and say that
x-intercept= 10
y-intercept= 1
*Cover-Up Method: If you were finding the X-intercept, you would just ignore the y variable and divide your whole number by x.
In this case the whole number is 1. 1/0.1=10
Vice Versa with finding the Y-intercept
Y + 0.4 = 2 .....subtract 0.4 from both sides
y = 2 - 0.4
y = 1.6 <==
The equation of a circle with center 
and radius 
is
In your case,
Plug these values into the generic formula and you'll get your equation.
Answer:
m=-15
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable. m=-15
