The common difference of the sequence 1/2, 1/4, 0, ... is: -1/4.

1/4 - 1/2 = 1/4 - 2/4 = - 1/4

0 - 1/4 = - 1/4

1/4 - 1/2 = 1/4 - 2/4 = - 1/4

0 - 1/4 = - 1/4

What is the slope of the line that is perpendicular to the line whose equation is 2x + y = 4.
-2
-1/2 **Weegy:** To find a slope in a easy way is to find to points in the line. So plugging in values will help. Plugging in x=1 yields value of y=2(1)+5 = 7, and then next plugging 2 as x, we get y= 2(2)+5=9; so we get two points (1,7) and (2,9) in the line. The formula to find out the slope is - m=(y2-y1)/(x2-x1), again plugging in just found values we get m=9-7/2-1=2/1=2 now things to remember when calculating slop of a line perpendicular to any line is that it has a negative slope regard to the given line, and one more thing is that value also become reciprocal.

The slope of the line that is perpendicular to the line whose equation is 2x + y = 4 is 1/2.

2x + y = 4

y = -2x + 4 so the slope of the line is -2.

The slope of its perpendicular line should be 1/2 since -2 * (1/2) = -1

2x + y = 4

y = -2x + 4 so the slope of the line is -2.

The slope of its perpendicular line should be 1/2 since -2 * (1/2) = -1
