The equation of the line that passes through the points (−3,5) and (0,−4) can be expressed in the form y=mx+b. What is the value of m+b?
The line is y = -10/3*x - 5, so m + b = -10/3 - 5 = -25/3.
That is not correct. Thank you though.
Slope of the line = (-4 - 5) / ( 0 - - 3) = -9 / 3 = -3
Using the point (0, -4) we have that
y = -3(x - 0) - 4
y = -3x - 4
m + b = -3 + (-4) = -7
That is correct!
Thank you.
