I. A sales representative for a publishing company recorded the following numbers of client contacts for the 36 days that he was on the road in the month of May. Use the given data to construct a grouped frequency distribution. Note: Use 6 for the desired number of classes. Find the following: a) range b) class interval c) frequency d) class boundaries e) relative frequency f) cumulative frequency g) midpoints

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

answer:

c) the x-coordinate of the center of the circle increases by 3
