Answer:
y = -5x - 21
Step-by-step explanation:
Use slope-intercept form:
y = mx + b
(-6,9) can be inputted as (x,y) so the equation turns to:
9 = m(-6) + b
since we also know that the slope is -5, the equation would turn into:
9 = (-5)(-6) + b
9 = 30 + b
b = -21
Since you now know b (aka the y-intercept) is -21, you can create an equation and input -21 for b:
y = -5x - 21
Hope this helps!
