Answer:
y = -3x - 12
Explanation:
y - 7 = -3x Put in the slope intercept form for a line
y = -3x + 7
Use the slope (-3), the x(-6) and the y(6) to find the y intercept and to write the equation for the line.
y = mx + b
6 = (-3)(-6) + b
6 = 18 + b Subtract 18 from both sides
-12 = b
y =mx + b
y = -3x -12
