3. Find the slope and y-intercept of the graph of the following equation.
2y + 4 = -6x

slope = -3, y-intercept y = -2

Step-by-step explanation:

Make y the subject of the line 2y + 4 = - 6xDivide throughout by two to get the slope of the graph as -3.Substitute x = 0 to get the y - intercept as y = -2

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
