Consider the line y = 1/4 - 5/4 x<br> Slope of a parallel line<br> Slope of a perpendicular line
gladu [14]

Answer:

parallel line slop2 = -5/4

perpendicular line slope = 4/5

Step-by-step explanation:

If 2 lines are parallel, they will have equal slopes.

Therefore, the slope of a line parallel to y = 1/4 - 5/4 x will be -5/4

If 2 lines are perpendicular, their slopes are negative reciprocals of each other.  So the slope of the perpendicular line = -1 ÷ -5/4 = 4/5

7.5 feet as a number
fenix001 [56]

Answer: 90 inches and 2.5 yards

Step-by-step explanation:

There are 12 inches in a foot. Since there are 7.5 feet, you will multiply 7.5 by 12 to get 90 inches.

7.5 x 12 = 90

There are 3 feet in a yard. Divide 7.5 by 3 to find the amount of yards.

7.5 / 3 = 2.5
