Tayne's math teacher assigned him 15 problems to do for homework. His mother makes a scatterplot of the time it takes him to work each problem. After 10 minutes, predict how many problems he will have left to do.

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)

they disappear if your absent from to long. i found out that the hard way.
