Answer:
- Slope: -2
- equation: y = -2x +5
Step-by-step explanation:
The given point is the y-intercept of the line, so the slope-intercept form of the equation of a line can be used:
   y = mx + b . . . . for slope m and y-intercept b
Here, you have the slope given as ...
   m = -2
   y-intercept = 5
so the equation of the line is ...
   y = -2x +5
_____
The y-intercept is the value of y when x=0. The point (x, y) = (0, 5) tells you the y-intercept is 5.
