Give the slope of each line. Also, state if the lines are parallel (yes or no). AB: y = - 3x + 4 and CD: y = - 3x -2 The slope of line AB: Slope of line CD: Are the lines parallel (yes or no):

Step-by-step explanation:

the slope is always the factor of x in the equation.

so, the slope of AB = -3, and the slope of CD = -3.

since these are equal, yes, the lines are parallel. parallel lines always have the same slope, and having the same slope means they are parallel.

they have different y axis intercepts (when x = 0), so they are not identical.
