Question

A line has a slope of $-7$ and contains the point $(3,0)$. The equation of this line can be written in the form $y = mx+b$. What is the value of $m+b$?

Answer 1

Answer:

  14

Step-by-step explanation:

In point-slope form, the equation with slope -7 through point (3, 0) can be written ...

  y = -7(x -3) +0

  y = -7x +21 . . . . . eliminate parentheses

Here, we can see m=-7 and b=21, so ...

  m+b = -7+21 = 14
