Y - y1 = m(x - x1) is the point slope equation.
y - 9 = 3(x - -2)
(9, -2)
Letter B
Answer:
rotation by 180°
Step-by-step explanation:
about its center, reflection across a diagonal, reflection across a line joining the midpoints of the nonparallel sides,rotation by 360° about its center. hope this helps you :)
To find the y-intercept plug a zero in for x and solve.
y = -3(0) - 9
y = -9
(0,-9) is how it would be written as an ordered pair.
