SLOPE return to index
The slope of an equation is the coefficient of x when the coefficient of y is one. In this problem 4y = 7x + 2 Seven is not the slope because the y coefficient is 4 Solve for y; y = 7/4 x + 2/4 The slope is 7/4
What is the slope of 3y = 6x + 9? answer
The slope of parallel lines are equal! Are the following lines parallel?
y = 3.5x + 6 and y = 3.5x - 6 answer
When multiplied together the slope of perpendicular lines are equal to negative one. Are the following lines perpendicular?
y = 3x + 7 and y = - 1/3 x + 2 answer
The graph of y = 3 is a horizontal line and the graph of x = 2 is a vertical line.
Horizontal and vertical lines are perpendicular to each other by the definition of vertical and horizontal lines
