Answer:
y = -2x - 6
Step-by-step explanation:
Use slope-intercept form to start the equation. y2 - y1 / x2 -x1
-6 - 0 / 0 - (-3) = -6 / 3 = m = -2
Then plug m (-2) into your y=mx+b equation.
y = -2x + b
substitute -6 for y value and 0 for x value to find value of b.
-6 = -2(0) + b
simplify
-6 = 0 +b
subtract 0 from both sides
-6 = b
plug b value back into the equation
final equation of line is: y = -2x -6
