Answer: y = -1/2x - 5
Step-by-step explanation:
Slope intercept form is y = mx + b
M = the slope, which is -1/2
Sub in 1/2 for m in y = mx + b
Point (0, -5) the x coordinate is 0, and the y coordinate is -5
Sub in -5 for y in y = mx + b
Sub in 0 for x in y = mx + b
Like this: (-5) = -1/2(0) + b
Now you only have one unknown so you can solve for b (the y intercept)
-5 = 0 + b
-5 = b
Final equation:
y =-1/2x - 5
