Answer: y = (-2/5)x -7
Explanation:
First find the slope of the line. (rise over run; 4/-10 or -4/10)
Then form the equation y = (-2/5)x + b
Then, find b, or the y-intercept. (plug in one of the points you were given to this equation)
-5 = (-2/5)(-5) + b
simplify
-5 = 2 + b
-7 = b
Re-write the first equation and substitute your value for b in
y = (-2/5)x -7
